Embodiment Construction
[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
[0037] In order to provide effective copyright protection for live content in theaters, the embodiments of the present invention use digital certificate technology to authorize and manage live content in theaters.
[0038] Digital certificates use the public key system, that is, use a pair of matching keys for encryption and decryption. Each user sets a specific private key (private key) known only to himself, and uses it for decryption and signature; at the same time, he sets a public key (public key) and discloses it to himself. Shared by group users for encryption...
