Abstract
A method, non-transitory computer readable medium and apparatus for decrypting a document are disclosed. For example, the method captures a tag on an encrypted document, transmits the tag to an application server of a communication network to request a per-document decryption key, receives the per-document decryption key if the tag is authenticated, and decrypts a portion of the encrypted document using a temporary decryption key contained in the tag, the tag decrypted with the per-document decryption key.
Claims20
A method comprising:
- registering, by an application server, with a communication network service provider of a communication network;
- receiving, by the application server, a master public key and a private signature key from the communication network service provider;
- receiving, by the application server, from a device of a user a request for a document;
- encrypting, by the application server, the document with a temporary key to generate an encrypted document;
- encrypting, by the application server, the temporary key with the master public key into a tag;
- generating, by the application server, a signed tag with the private signature key and the tag;
- and
- sending, by the application server, the encrypted document and the signed tag to the device of the user.
A tangible computer-readable medium storing a plurality of instructions, which when executed by a processor of an application server, cause the processor to perform operations, the operations comprising:
- registering with a communication network service provider of a communication network;
- receiving a master public key and a private signature key from the communication network service provider;
- receiving from a device of a user a request for a document;
- encrypting the document with a temporary key to generate an encrypted document;
- encrypting the temporary key with the master public key into a tag;
- generating a signed tag with the private signature key and the tag;
- and
- sending the encrypted document and the signed tag to the device of the user.
