The proposed deliverable specifies the basic principles and methodology to be used to recognize personal data written in free text in different languages and countries. The applications are essentially for protecting human data circulating in national and international industries, and private and public organizations. The principles of data protection should apply to any information concerning an identified or identifiable natural person. An identifiable natural person is one who can be identified, directly or indirectly, in particular for the proposed standard by reference to an identifier such as, for example, a name, an identification number, a bank account number, location data such as residence address, an online identifier. Excluded from this standard are factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person. The proposed deliverable which is directed to processing by human beings and/or automated processing is also applicable to different domains (for example: law, finance, health, etc.) but excludes automated image processing.
