The invention discloses an encrypted document leakage automatic alarming method. The method includes: establishing a unique identifier for each protected document, and setting the unique identifier of the document in the document; uploading the unique identifier of the document to a cloud server, allowing the cloud server to use the unique identifier as an index to store encryption information corresponding to each document; uploading the unique identifier of the document and current encryption information to the cloud server through a third part DRM system while the third part DRM system encrypts the document, and allowing the cloud server to update the encryption information of the document; automatically uploading the unique identifier of the document and the encryption information to be checked to the cloud server while a user opens the document at a document reading client; allowing the cloud server to determine if encryption information stored in a database and the encryption information to be checked is consistent or not according to the unique identifier after the information uploaded by the document reading client is received, and allowing the cloud server to automatically send alarm information to a document copyright owner if the encryption information stored in the database and the encryption information to be checked is not consistent and the document may be decrypted.
Description
technical field [0001] The invention relates to the field of digital copyright protection, in particular to a method for automatically calling the police after an encrypted document is leaked. Background technique [0002] Digital Rights Management (DRM) is to use a certain calculation method to realize the protection of digital content, prevent illegal copying of digital content, or make copying difficult and costly. End users must obtain authorization Digital content can only be used; the use of digital content by users is carried out under the constraints specified by the DRM system. DRM technology mainly considers the use of technical means in advance to prevent files from being illegally distributed. But if the document is really illegally cracked and used, how can we be reminded immediately afterwards and take possible remedial measures? Existing DRM systems basically do not have the function of reminding after the event. Contents of the invention [0003] The inv...
