Computer data embedding method, computer data displaying method and computer data embedding and displaying device

Abstract

The invention provides a computer data embedding and displaying method as well as a computer data embedding and displaying device. The computer data embedding and displaying device comprises a recording part 701, an associating part 702, a mapping part 703, a displaying part 704 and an updating part 705; the recording part 701 records identity information; the associating part 702 obtains the identity information provided by the recording part 701 and associates the identity information with time information; the mapping part 703 obtains the associated identity information and time information provided by the associating part 702 and performing character string mapping; the displaying part 704 receives information after being mapped by the mapping part 703 and displays the mapped information; and the updating part 705 is used for updating the time information and providing the time information to the associating part 702. In the technology provided by the invention, through regional encryption, storage cost and time cost required by decryption are saved, reliability of reverse tracing is also added, and a visual effect of normal chatting is not affected.

Description

technical field [0001] The invention relates to a computer data embedding method, a display method and a device thereof, in particular to a method and a device for embedding and displaying watermark information including identity information and time information in real time in a chat window of a chat tool. Background technique [0002] As an effective method of digital media copyright protection and identity verification, digital watermarking has aroused great interest and attention in the world in recent years. With the development and popularization of digital technology and the Internet, digital works are becoming more and more abundant, but they are also facing a new problem—malicious information leakage. The existing password encryption technology guarantees the security of information communication on the Internet to a large extent, that is, by encrypting data files into ciphertext and publishing them, so as to achieve the purpose of copyright protection and informati...

AI Technical Summary

Problems solved by technology

[0005] However, there are the following technical problems in the existing technical solutions: the time cost and storage cost of decryption are high, and the watermark is easy to identify, which will be easier to avoid or cause resistance to users; and it cannot support partial decoding to increase traceability. Reliability; the possibility of traceability cannot be improved through fuzzy queries; the displayed style cannot reach the maximum coverage; the display of the watermark will affect the reading and visual experience; the information of the watermark cannot be updated in real time, and the amount of information is small; the watermark cannot be played in dynamic scrolling display in the form of
