Identity theft is a crime in which an imposter obtains key pieces of personal information, such as Social Security or driver's license numbers, in order to impersonate someone else. The information can be used to obtain credit, merchandise, and services in the name of the victim, or to provide the thief with false credentials.
Data theft is the illegal transfer or storage of any information that is confidential, personal, or financial in nature, including passwords, software code, or algorithms, proprietary process-oriented information, or technologies. Considered a serious security and privacy breach, the consequences of data theft can be severe for individuals and businesses.
