Personally Identifiable Information (PII)
The protection of PII is important to maintain public trust and confidence in an organization, to protect the reputation of an organization, and to protect against legal liability for an organization. Organizations have always considered trust, confidence, and reputation as motivating factors in protecting PII. Recently, organizations have become more concerned about the risk of legal liability due to the enactment of many US federal, state, and international privacy laws.

India Privacy Laws

UK Data Protection Act 1998
The Data Protection Act 1998 (DPA) is a United Kingdom Act of Parliament which defines UK law on the processing of data on identifiable living people. It is the main piece of legislation that governs the protection of personal data in the UK. Although the Act itself does not mention privacy, it was enacted to bring UK law into line with the European Directive of 1995 which required Member States to protect people's fundamental rights and freedoms and in particular their right to privacy with respect to the processing of personal data. In practice it provides a way for individuals to control information about themselves.
United States privacy law embodies several different legal concepts. One is the invasion of privacy, a tort based in common law allowing an aggrieved party to bring a lawsuit against an individual who unlawfully intrudes into his or her private affairs, discloses his or her private information, publicizes him or her in a false light, or appropriates his or her name for personal gain. Public figures have less privacy, and this is an evolving area of law as it relates to the media.
The essence of the law derives from a right to privacy, defined broadly as "the right to be let alone." It usually excludes personal matters or activities which may reasonably be of public interest, like those of celebrities or participants in newsworthy events. Invasion of the right to privacy can be the basis for a lawsuit for damages against the person or entity violating the right. These include the Fourth Amendment right to be free of unwarranted search or seizure, the First Amendment right to free assembly, and the Fourteenth Amendment due process right, recognized by the Supreme Court as protecting a general right to privacy within family, marriage, motherhood, procreation, and child rearing.
