Description

Method for encrypting mobile hard disk and data storing encrypted voice and image data

The present invention relates to a mobile hard disk, and more particularly to a mobile hard disk in which voice, image, and encryption functions are stored. Background technique

As the IT industry moves forward rapidly, more and more hardware with storage functions and more and more functions are provided, which brings great convenience to users. People also like the full-featured storage hardware. Due to the emergence of mobile hard disks, people can store more large-capacity data files on the mobile hard disk, making it easy to save data and move data.

Although the mobile hard disk currently used can store a large number of data files, it is also convenient to carry, but it cannot prevent the user from copying the data files in the mobile hard disk, and it is easy to make the contents of the hard disk stolen, difficult to keep secret and copy in large quantities. Of course, when using the hard disk, we can set the password of the document through the computer so that the document can only be read and cannot be copied. However, this setting can be easily cracked, and the content on the mobile hard disk is still easily stolen. Modern life has many voices, images, texts, etc. that need to be protected, such as songs sung by stars, cross talks of performances, essays, TV series, movies, etc. Although they can protect the creators' labor results through legal forms such as copyright, this is only the last resort when rights holders are infringed. Therefore, how to protect the copyright of voice, image and text in technology has become a difficult problem for people to overcome.

At present, mobile hard disks appearing on the market are generally empty, and there is nothing in the mobile hard disk. After buying the mobile hard disk, people can load music, movies, TV dramas, novels, and various textbooks into the mobile hard disk. Nowadays, people expect a mobile hard disk that contains original music, movies, novels, textbooks, and other voice and image numbers. This kind of mobile hard disk can completely protect the originality of various contents in the mobile hard disk through internal encryption. In other words, we can purchase the copyright of the author by signing a contract or agreement with the copyright owner, and then store the contents of various copyrights on the mobile hard disk, and protect the music, movies, and movies in the mobile hard disk through encryption. Content such as text can be enjoyed by the purchaser and prevented from being copied in large quantities. Thus, the shift in sales in the market The hard disk may not be an empty disk, but a solid disk containing various data contents such as voice, image number, and the like, and the real disk can completely protect the copyright of the author. In this way, the sale of this firm is not only the content of the sales firm, but more importantly, it can help the author realize the economic rights in the copyright through the sales firm. Therefore, we can not only crack down on various piracy in the market, but also protect the author's copyright more powerfully. Summary of the invention

The object of the present invention is to overcome the defects of the existing mobile hard disk, and to provide a data file capable of storing voice, image digital and the like and encrypt the data file to protect the originality of the content in the mobile hard disk, thereby realizing the copyright owner and the producer. Permits can only be read, cannot be copied or modified by the mobile hard disk.

Another object of the present invention is to provide a mobile hard disk which can not only input and store data files such as encrypted voices and image numbers, but also output them to various receiving devices.

A third object of the present invention is to provide a method for compacting a mobile hard disk storing encrypted voice and image data.
