A SYSTEM OF MANAGING SHARED DATA IN THE SMART PHONE BY USING COUPLE FINGER-PRINTS

摘要

The present invention relates to a system for managing shared data in a smartphone by using couple fingerprints which controls access through fingerprint recognition by at least one person, except for the smartphone owner, with respect to the shared data stored in the smartphone. The present invention may include: a fingerprint registration unit which registers at least one fingerprint except for that of the smartphone owner as a group; a data management unit which stores the shared data after encryption and permits access by decoding the shared data only when the user authentication is passed; a user authentication unit which is inputted with all fingerprints registered in the group and authenticates the access to the shared data by checking whether the fingerprint corresponds to the fingerprint in the group; and an encoding-decoding unit which encodes or decodes the shared data with encryption keys which are produced by the fingerprints registered in the group. By recognizing character codes of issued documents with an optical character recognition, data access is allowed only after fingerprint recognition of at least one person except for the smartphone owner, therefore, even if the data is stored in another person′s smartphone, data access is allowed only with the user′s agreement.
