SYSTEM AND METHOD OF STORING DATA IN JPEG FILES

摘要

The present invention comprises a system for communicating image data and other data. The system comprises a JPEG file (32) having a JPEG data, at least one non-JPEG data (104), and a computer. The computer is programmed to read a predetermined number of sequential bytes of the non-JPEG data (104). The computer is also programmed to determine position of each byte in the sequential bytes that contain a JPEG marker and determine a locator byte, which is capable of indicating the position of any bytes in the sequential bytes that contain a JPEG marker. The computer is further programmed to write the locator byte in the JPEG file (32) and write encoded bytes in the JPEG file (32). The computer writes the encoded bytes in the JPEG file (32) in a manner wherein, for each byte in the sequential bytes, if the byte does not contain a JPEG marker, each byte is replaced with a bit, preferably written as 0, in the order of the byte's occurrence in the sequential bytes. If the byte does contain a JPEG marker, the byte containing a JPEG marker is replaced with a place holder bit, preferably written as 1 and in the order of the byte's occurrence in the sequential bytes.
