System and method for secure reciprocal exchange of data

摘要

A system for transmission of data between a first device operated by a first user and a second device operated by a second user includes a database that receives a first set of data input by the first user and a second set of data input by the second user. In one embodiment, the second user can access at least a first portion of the first set of data from the database only after the second user authorizes the first user to access at least a first portion of the second set of data from the database. In another embodiment, the first set of data includes an immediate mode of access and/or one or more future modes of access of the first user which correlate to one or more specific time periods during which the future mode of access will become the immediate mode of access. Additionally, the first set of data can include a time-dependent schedule of the future mode of access of the first user. The second device can be a mobile phone having a memory that is automatically updated by the database with data input by the first user. Moreover, the first user can specify a hierarchical privacy level for one or more data fields, and a correlative hierarchical clearance level to the second user. The clearance level is compared with the first privacy level to determine whether the second user has access to any of the data fields.
