In law, fraud is deliberate deception to secure unfair or unlawful gain, or to deprive a victim of a legal right. Fraud itself can be a civil wrong (i.e., a fraud victim may sue the fraud perpetrator to avoid the fraud or recover monetary compensation), a criminal wrong (i.e., a fraud perpetrator may be prosecuted and imprisoned by governmental authorities) or it may cause no loss of money, property or legal right but still be an element of another civil or criminal wrong. The purpose of fraud may be monetary gain or other benefits, such as obtaining a passport or travel document, driver's license or qualifying for a mortgage by way of false statements.
A hoax is a distinct concept that involves deliberate deception without the intention of gain or of materially damaging or depriving a victim.
In common law jurisdictions, as a civil wrong, fraud is a tort. While the precise definitions and requirements of proof vary among jurisdictions, the requisite elements of fraud as a tort generally are the intentional misrepresentation or concealment of an important fact upon which the victim is meant to rely, and in fact does rely, to the harm of the victim. Proving fraud in a court of law is often said to be difficult. That difficulty is found, for instance, in that each and every one of the elements of fraud must be proven, that the elements include proving the states of mind of the perpetrator and the victim, and that some jurisdictions require the victim to prove fraud by clear and convincing evidence.
The remedies for fraud may include rescission (i.e., reversal) of a fraudulently obtained agreement or transaction, the recovery of a monetary award to compensate for the harm caused, punitive damages to punish or deter the misconduct, and possibly others.
Fraud may serve as a basis for a court to invoke its equitable jurisdiction.
In common law jurisdictions, as a criminal offence, fraud takes many different forms, some general (e.g., theft by false pretense) and some specific to particular categories of victims or misconduct (e.g., bank fraud, insurance fraud, forgery). The elements of fraud as a crime similarly vary. The requisite elements of perhaps most general form of criminal fraud, theft by false pretense, are the intentional deception of a victim by false representation or pretense with the intent of persuading the victim to part with property and with the victim parting with property in reliance on the representation or pretense and with the perpetrator intending to keep the property from the victim.
Section 380(1) of the Criminal Code provides the general definition for fraud in Canada:
380. (1) Every one who, by deceit, falsehood or other fraudulent means, whether or not it is a false pretence within the meaning of this Act, defrauds the public or any person, whether ascertained or not, of any property, money or valuable security or any service,
- (a) is guilty of an indictable offence and liable to a term of imprisonment not exceeding fourteen years, where the subject-matter of the offence is a testamentary instrument or the value of the subject-matter of the offence exceeds five thousand dollars; or
- (b) is guilty
- (i) of an indictable offence and is liable to imprisonment for a term not exceeding two years, or
- (ii) of an offence punishable on summary conviction, where the value of the subject-matter of the offence does not exceed five thousand dollars.
In addition to the penalties outlined above, the court can also issue a prohibition order under s. 380.2 (preventing a person from "seeking, obtaining or continuing any employment, or becoming or being a volunteer in any capacity, that involves having authority over the real property, money or valuable security of another person"). It can also make a restitution order under s. 380.3.
The Canadian courts have held that the offence consists of two distinct elements:
The Supreme Court of Canada has held that deprivation is satisfied on proof of detriment, prejudice or risk of prejudice; it is not essential that there be actual loss. Deprivation of confidential information, in the nature of a trade secret or copyrighted material that has commercial value, has also been held to fall within the scope of the offence.
Zhang Yingyu's story collection The Book of Swindles (ca. 1617) testifies to rampant commercial fraud, especially involving itinerant businessmen, in late Ming China. The journal Science reported in 2017 that fraud is rife in Chinese academia, resulting in numerous article retractions and harm to China's international prestige.The Economist, CNN, and other media outlets regularly report on incidents of fraud or bad faith in Chinese business and trade practices.Forbes cites cybercrime as a persistent and growing threat to Chinese consumers.
"Half of all UK companies say that they have been the victim of fraud or of economic crime in the last two years [2016-2018], according to a major survey conducted by professional services firm PwC." 
In January 2018 the Financial Times reported that the value of UK fraud hit a 15-year high of £2.11bn in 2017 according to a study. The article said that the accountancy firm BDO examined reported fraud cases worth more than £50,000 and found that the total number rose to 577 in 2017, compared with 212 in 2003. The study found that the average amount stolen in each incident rose to £3.66m, up from £1.5m in 2003. 
As at November 2017 Fraud is the most common criminal offence in the UK according to a study by Crowe Clark Whitehill, Experian and the Centre for Counter Fraud Studies.  The study suggests the UK loses over £190 billion per year to fraud. £190 billion is more than 9% of the UK's projected GDP for 2017 ($2,496 (£2,080) billion according to Statistics Times). The estimate for fraud in the UK figure is more than the entire GDP of countries such as Romania, Qatar and Hungary. 
According to another review by the UK anti-fraud charity Fraud Advisory Panel (FAP), business fraud accounted for £144bn, while fraud against individuals was estimated at £9.7bn. The FAP has been particularly critical of the support available from the police to victims of fraud in the UK outside of London. Although victims of fraud are generally referred to the UK's national fraud and cyber crime reporting centre, Action Fraud, the FAP found that there was "little chance" that these crime reports would be followed up with any kind of substantive law enforcement action by UK authorities, according to the report.
In July 2016 it was reported that fraudulent activity levels in the UK increased in the 10 years to 2016 from £52 billion to £193bn. This figure would be a conservative estimate, since as the former commissioner of the City of London Police, Adrian Leppard, has said, only 1 in 12 such crimes are actually reported. Donald Toon, director of the NCA's economic crime command, stated in July 2016: "The annual losses to the UK from fraud are estimated to be more than £190bn". Figures released in October 2015 from the Crime Survey of England and Wales found that there had been 5.1 million incidents of fraud in England and Wales in the previous year, affecting an estimated one in 12 adults and making it the most common form of crime.
Also in July 2016, the Office for National Statistics (ONS) stated "Almost six million fraud and cyber crimes were committed last year in England and Wales and estimated there were two million computer misuse offences and 3.8 million fraud offences in the 12 months to the end of March 2016." Fraud affects one in ten people in the UK. According to the ONS most frauds relate to bank account fraud. These figures are separate from the headline estimate that another 6.3 million crimes (distinct from frauds) were perpetrated in the UK against adults in the year to March 2016.
Fraud is apparently low on the list UK law enforcement priorities. Controversially, the crime does not feature on a new "Crime Harm Index" published by the Office for National Statistics. Michael Levi, professor of criminology at Cardiff University, remarked in August 2016 that it was 'deeply regrettable' fraud is being left out of the first index despite being the most common crime reported to police in the UK. Professor Levi said 'If you've got some categories that are excluded, they are automatically left out of the police's priorities.'. The Chief of the National Audit Office (NAO), Sir Anyas Morse has also said "For too long, as a low-value but high-volume crime, online fraud has been overlooked by government, law enforcement and industry. It is now the most commonly experienced crime in England and Wales and demands an urgent response."
The Fraud Act 2006 (c 35) is an Act of the Parliament of the United Kingdom. It affects England and Wales and Northern Ireland. It was given Royal Assent on 8 November 2006, and came into effect on 15 January 2007.
The Act gives a statutory definition of the criminal offence of fraud, defining it in three classes--fraud by false representation, fraud by failing to disclose information, and fraud by abuse of position. It provides that a person found guilty of fraud is liable to a fine or imprisonment for up to twelve months on summary conviction (six months in Northern Ireland), or a fine or imprisonment for up to ten years on conviction on indictment. This Act largely replaces the laws relating to obtaining property by deception, obtaining a pecuniary advantage and other offences that were created under the Theft Act 1978.
The Serious Fraud Office (United Kingdom) is an arm of the Government of the United Kingdom, accountable to the Attorney-General.
The National Fraud Authority (NFA) is the government agency co-ordinating the counter-fraud response in the UK.
Cifas is the UK's leading fraud prevention service, a not-for-profit membership organisation for all sectors that enables organisations to share and access fraud data using their databases. Cifas is dedicated to the prevention of fraud, including internal fraud by staff, and the identification of financial and related crime.
A Cifas study found that the number of reported cases of identity fraud jumped by 57 per cent between 2014 and 2015. Drawing from its reporting database of 261 organisations, Cifas found that 148,463 people reported having their identity stolen in 2015, up from 94,492 the previous year. The rise of social media has been blamed. Cifas has warned that social media sites such as Facebook, Twitter and LinkedIn are becoming a "hunting ground" for fraudsters.
In July 2016 the BBC referred to a recently published Cifas report which estimated the annual cost of fraud in the UK was £193bn - equal to nearly £3,000 per head of population.
In March 2017, Cifas reported that identity fraud had reached "record levels", with 173,000 cases recorded to its fraud database in 2016 - the highest number ever recorded by members of Cifas. That trend continued through 2017, with Cifas reporting more than 89,000 cases of identity fraud in the first six months of the year.
Cifas data from 2016 and 2017 also highlighted the growing issue of 'money mules' - people who allow their bank accounts to be used to launder money. Cifas reported that the number of young people (18-24-year-olds) allowing their accounts to be used to transfer the proceeds of crime had risen by an unprecedented 75 per cent in the last year.
The proof requirements for criminal fraud charges in the United States are essentially the same as the requirements for other crimes: guilt must be proved beyond a reasonable doubt. Throughout the United States fraud charges can be misdemeanors or felonies depending on the amount of loss involved. High value frauds can also include additional penalties. For example, in California losses of $500,000 or more will result in an extra two, three, or five years in prison in addition to the regular penalty for the fraud.
The U.S. government's 2006 fraud review concluded that fraud is a significantly under-reported crime, and while various agencies and organizations were attempting to tackle the issue, greater co-operation was needed to achieve a real impact in the public sector. The scale of the problem pointed to the need for a small but high-powered body to bring together the numerous counter-fraud initiatives that existed.
According to Bloomberg, auto loan application fraud rates in the United States has been steadily rising over the past few years. This type of fraud expected to double from about $2-3 billion in 2015 to $4-6 billion in 2017.
Although elements may vary by jurisdiction and the specific allegations made by a plaintiff who files a lawsuit that alleged fraud, typical elements of a fraud case in the United States are that:
To establish a civil claim of fraud, most jurisdictions in the United States require that each element of a fraud claim be plead with particularity and be proved by a preponderance of the evidence, meaning that it is more likely than not that the fraud occurred. Some jurisdictions impose a higher evidentiary standard, such as Washington State's requirement that the elements of fraud be proved with clear, cogent, and convincing evidence (very probable evidence), or Pennsylvania's requirement that common law fraud be proved by clear and convincing evidence.
The measure of damages in fraud cases is normally computed using one of two rules:
The typical organization loses five percent of its annual revenue to fraud, with a median loss of $160,000. Frauds committed by owners and executives were more than nine times as costly as employee fraud. The industries most commonly affected are banking, manufacturing, and government.
Fraud can be committed through many media, including mail, wire, phone, and the Internet (computer crime and Internet fraud). International dimensions of the web and ease with which users can hide their location, the difficulty of checking identity and legitimacy online, and the simplicity with which hackers can divert browsers to dishonest sites and steal credit card details have all contributed to the very rapid growth of Internet fraud. In some countries, tax fraud is also prosecuted under false billing or tax forgery. There have also been fraudulent "discoveries", e.g., in science, to gain prestige rather than immediate monetary gain.
Beyond laws that aim at prevention of fraud, there are also governmental and non-governmental organizations that aim to fight fraud. Between 1911 and 1933, 47 states adopted the so-called Blue Sky Laws status. These laws were enacted and enforced at the state level and regulated the offering and sale of securities to protect the public from fraud. Though the specific provisions of these laws varied among states, they all required the registration of all securities offerings and sales, as well as of every U.S. stockbroker and brokerage firm. However, these Blue Sky laws were generally found to be ineffective. To increase public trust in the capital markets the President of the United States, Franklin D. Roosevelt, established the U.S. Securities and Exchange Commission (SEC). The main reason for the creation of the SEC was to regulate the stock market and prevent corporate abuses relating to the offering and sale of securities and corporate reporting. The SEC was given the power to license and regulate stock exchanges, the companies whose securities traded on them, and the brokers and dealers who conducted the trading.
For detection of fraudulent activities on the large scale, massive use of (online) data analysis is required, in particular predictive analytics or forensic analytics. Forensic analytics is the use of electronic data to reconstruct or detect financial fraud. The steps in the process are data collection, data preparation, data analysis, and the preparation of a report and possibly a presentation of the results. Using computer-based analytic methods Nigrini's wider goal is the detection of fraud, errors, anomalies, inefficiencies, and biases which refer to people gravitating to certain dollar amounts to get past internal control thresholds.
The analytic tests usually start with high-level data overview tests to spot highly significant irregularities. In a recent purchasing card application these tests identified a purchasing card transaction for 3,000,000 Costa Rica Colons. This was neither a fraud nor an error, but it was a highly unusual amount for a purchasing card transaction. These high-level tests include tests related to Benford's Law and possibly also those statistics known as descriptive statistics. These high-tests are always followed by more focused tests to look for small samples of highly irregular transactions. The familiar methods of correlation and time-series analysis can also be used to detect fraud and other irregularities. Forensic analytics also includes the use of a fraud risk-scoring model to identify high risk forensic units (customers, employees, locations, insurance claims and so on). Forensic analytics also includes suggested tests to identify financial statement irregularities, but the general rule is that analytic methods alone are not too successful at detecting financial statement fraud.
Apart from fraud, there are several related categories of intentional deceptions that may or may not include the elements of personal gain or damage to another individual:
If the pattern of related felony conduct involves the taking of, or results in the loss by another person or entity of, more than five hundred thousand dollars ($500,000), the additional term of punishment shall be two, three, or five years in the state prison.
