This invention provides a method, apparatus, electronic device, and storage medium for embedding image watermarks. The method includes: acquiring encrypted data and license information of a target image; wherein the license information includes a decryption key; decrypting the encrypted data using the decryption key with digital rights management (DRM) software to obtain the original image data and original metadata of the target image; wherein the original metadata includes color information of the target image; embedding watermark information into the original metadata using the DRM software to obtain embedded metadata; and outputting the watermark-embedded data of the target image using the DRM software; the watermark-embedded data includes the embedded metadata. This method can achieve reasonable watermark embedding to reduce the possibility of image leakage.

Embodiments of the present application disclose a playing method, a communication device, a storage medium, a chip and a system, which are used for improving security of watermark adding and success rate of watermark adding. Embodiments of the present application provide a playing method, the method is applied to a client, and the method comprises the following steps: sending an authorization request message to a server, the authorization request message is used for requesting the server to authorize the client to use first data, the first data is digital media content encrypted by digital rights management (DRM); receiving an authorization response message from the server, the authorization response message comprises an encryption key corresponding to the first data and a first parameter corresponding to the first data, the first parameter is used for indicating a watermark control function; decrypting the first data according to the encryption key to obtain decrypted digital media content; controlling a watermark in the digital media content according to the first parameter, and playing the digital media content.

A decoding device includes a communication interface and a processor operatively coupled to the communication interface. The communication interface receives at least a portion of a broadcast stream containing media data, including media samples. The processor identifies information elements containing DRM processing information within the broadcast stream. Each information element is associated with a corresponding media sample from the media data. For each information element, the processor also identifies the media sample associated with that information element. Based on the information element, the processor further identifies the DRM processing information for that media sample. Finally, the processor decodes the media sample based on the DRM processing information.

Embodiments of this application provide a digital rights management DRM method, apparatus, and system, to implement a DRM interworking operation between DRM servers and clients of different vendors. The method includes: A DRM server encrypts a first media file by using a first encryption method to obtain a first encrypted media file; the DRM server generates content protection description information of the first encrypted media file, where the content protection description information includes a content identifier and encryption method information, the content identifier identifies the first encrypted media file, and the encryption method information identifies the first encryption method; the DRM server performs first formatting on the content protection description information to generate formatted content protection data; the DRM server encapsulates the formatted content protection data to generate a content protection data packet.

The application provides a kind of based on consumption gift and dynamic bottom pool settlement contribution value transaction and cashing processing method, it is related to internet e-commerce and digital rights management technical field.The method comprises the following steps: step 1, user contribution value acquisition: after user completes purchase behavior in platform, system sends contribution value to user according to 10% of user actual payment amount, the contribution value sent is counted into the total number of user personal account contribution value, while all the contribution value obtained by all users is accumulated, to form the total contribution value number of platform;Step 2, income bottom pool establishment: platform extracts funds from its own operating income into contribution value income bottom pool, to form total bottom pool amount, the operating income includes at least one of commodity sales income, transaction commission, service charge.The realization user contribution and platform income synchronous binding, improve user stickiness and platform sustainable operation ability, guarantee the transparent accuracy of cashing settlement, form "consumption→gift value→value-added→cashing" closed-loop incentive system.

A processing system employs system hardware to secure different DRM channels. The processing system employs an architecture including a root-of-trust (RoT) processor that assigns different keyspaces to different DRM channels. The processing system further includes one or more security gaskets that employ the assigned keyspaces to isolate the different DRM channels from each other. The security gasket receives a transaction targeting a DRM pipeline and allows the transaction to proceed based on a keyspace identified by the transaction and a keyspace assigned to the DRM.

Non-fungible token (NFT) platforms in accordance with various embodiments of the invention are described. In an embodiment of the NFT platform includes generating an instant NFT that includes data, at least one record, and a first timestamp, where the instant NFT is privately maintained and not publicly accessible; determine a modification to the at least one record associated with the instant NFT to generate several records associated with the instant NFT, where the modification is indicative of a transaction associated with the instant NFT; protect the instant NFT and the modification to the at least one record associated with the instant NFT, where the modification to the at least one record is associated with a second timestamp; detect an indication to mint the instant NFT as an NFT; and mint the instant NFT as an NFT on a public blockchain.
