This application provides an online-streamer image model file transmission method and computing device in co-hosting during livestreaming. The method includes: receiving an online-streamer image model file sent by a first online streamer end, and obtaining a target obfuscation key and a target encryption type; determining to-be-encrypted bytes in the online-streamer image model file based on the target encryption type, and encrypting the to-be-encrypted bytes based on the target obfuscation key to obtain an encrypted online-streamer image file; and receiving an interaction request between the first online streamer end and a second online streamer end, and sending the encrypted online-streamer image file to the second online streamer end based on the interaction request.

This application provides an image model file transmission method and computing device. The method includes: receiving an image model file of a first online streamer that is sent by a first client; obtaining a target key, and encrypting the image model file based on the target key to obtain an encrypted image model file; in response to determining that an interaction request for the first online streamer and a second online streamer is received, sending the encrypted image model file to a second client based on an online streamer identifier of the second online streamer that is carried in the interaction request; and in response to determining that a decryption request sent by the second client is received, sending the target key to the second client, where the target key is used by the second client to decrypt the encrypted image model file to obtain the image model file.

This application provides an online streamer image picture transmission method and computing device in live interaction. The method applied to a server, the method includes: receiving an online streamer image picture sent by a first online streamer end, and obtaining a target obfuscation key; performing encryption processing on the online streamer image picture based on the target obfuscation key and picture information of the online streamer image picture, to obtain an encrypted online streamer image picture; and in response to determining that a live interaction request for the first online streamer end and a second online streamer end is received, sending the encrypted online streamer image picture and the target obfuscation key to the second online streamer end.

Provided is a video playback system based on approval of a playback approver. A decryption key that can decrypt an encrypted and stored recorded video is generated only when video playback is approved by a playback approver using an appointed playback approval method and transmitted to the video recording device so that it is possible to prevent leakage of the recorded video with sensitive personal information.

A method and apparatus for secure multimedia transfer provides an encrypted data transfer system that makes transferring multimedia content from a client to any incompatible system or to a system outside the location of the client very difficult.

A source device for transmitting content to a sink device is provided. The source device may include an interface configured to perform high-bandwidth digital content protection (HDCP) authentication with the sink device, and a controller configured to determine an HDCP version supported by the sink device, convert the content so as to be encrypted in the HDCP version supported by the sink device in response to a determination that another HDCP version applied to the content is not supported by the sink device, encrypt the converted content in the HDCP version supported by the sink device, and control the interface to transmit the content to the sink device.
