Abstract: A system, process and article of manufacture includes the generation of a “BIG Data” set of searchable submissions of biographical and/or physical identity inputs by interested persons with knowledge of deceased third parties; or by self-disclosing individuals to be released either during the lifetime of the submitter (Inter-Vivos) or Post Mortem (PM), each knowing that the consequent anonymous Big Data set comprised of all released submissions will be made accessible to researchers. Submissions are solicited via proprietary questionnaires, developed and rigorously validated using established techniques in behavioral science, statistics and informatics. Since data contained in questionnaire(s) enters the proprietary Big Data set if and when the subject of the questionnaire is dead, a key element of the process is the opportunity for living family members or friends to complete an initial proprietary questionnaire to preserve for the deceased a “Continuity of Identity.
