Abstract: The present invention provides, in at least one embodiment, a system and method for management of digital information using an individual digital watermark. The system facilitates and controls engagements between an individual and other individuals or businesses. The system uses processing software to register an individual. The system stores an individual's profile and preference information in a database of digital information. When the individual makes contact with another entity (e.g., business or another individual) that he would like to connect with or share information with from his database, the individual allows his device to be scanned using a scanner (e.g., microphone or camera) such that the other entity can extract the embedded individual digital watermark and unlock access to a category of the individual's database of preselected digital information.
