Information embedding method and apparatus
First Claim
1. A method of embedding information in original data of an original image, the method comprising the steps of:
- storing supplementary photographic information related to the original image in predetermined storage separate from the original image data;
generating storage management location information indicating where the supplementary photographic information has been stored; and
embedding the storage management location information within the original data, wherein the supplementary photographic information is at least one selected from the group consisting of a photographed scene, light source information, exposure correction, and color fog correction.

Abstract
Supplementary information related to original data is embedded in the original data without being lost or altered and without degrading the quality of the original data. A photographing condition or the like regarding photographing of the original image data is generated as the supplementary information by supplementary information generating means and stored in a database on a network by supplementary information storing means. Storage management information such as a URL address of where the supplementary information is stored is generated by storage management information generating means and embedded by embedding means in the original image data by using deep layer encryption. The original image data in which the storage management information has been embedded are recorded in a recording medium. Since the storage management information has a smaller amount of data than the supplementary information, quality of the original data is prevented from being degraded even when the storage management information is embedded in the original image data.
