A system, method, computer program product, and service for encrypting a message. A plaintext message to be encrypted is received as input data into a computer. A processor on the computer encrypts the plaintext message, using a public key having two components, each component having degree 4. The encrypted version of the input plaintext message is output as a ciphertext having two components, each component having degree 4.

System and method for quantum resistant public key encryption

A method and device for identifying a state, electronic device and computer-readable storage medium are provided. The method includes: acquiring a to-be-detected image for a specific scene and determining a region of interest in the to-be-detected image; the region of interest being a region obtained by subtracting an occlusion range of the storage container in a closed state from an occlusion range in an open state; determining a positional relation between the region of interest and specific object regions where the specific objects are positioned in the to-be-detected image; determining at least one value based on values of pixels in the region of interest, when the positional relation represents that there is no specific object region partially overlapping the region of interest; and determining whether the storage container is in an open state or closed state based on the at least one value and a preset value range.

Method and device for identifying state, electronic device and computer -readable storage medium

The present disclosure relates to an image processing method and apparatus, an electronic device, and a storage medium. The method includes: obtaining video streams of a game tabletop; detecting target objects in a plurality of image frames included in the video streams; determining a current game stage based on the target objects; and determining game detecting results according to the target objects and the determined game stage.

Image processing method, apparatus, and non-transitory computer readable storage medium

An example operation may include one or more of splitting an encrypted file into a plurality of file fragments, distributing the file fragments to a plurality of storing peers for storing the file fragments off-chain, splitting an encryption key used to encrypt the file into a plurality of key fragments, encrypting each key fragment using a public key of a different storing peer, and storing the respectively encrypted key fragments on the distributed ledger such that each encrypted key fragment is associated with the encrypted file.

Blockchain for on-chain management of off-chain storage

An example method of operation may include one or more of identifying one or more votes in a distributed voting configuration, dividing each of the one or more votes into a plurality of partial votes, such that each of the one or more votes comprises two or more partial votes, randomly distributing the plurality of partial votes to a plurality of peer nodes associated with a blockchain, and receiving a broadcast from each of the peer nodes based on a distributed tally of the plurality of partial votes.
