An example method of performing interactive videogame verification using cryptographically protected transaction records includes: receiving, by a videogame server, from a first videogame client device, a first transaction record reflecting a first set of events associated with an interactive videogame session, wherein the first transaction record is cryptographically signed by a first private cryptographic key associated with the first videogame client device; receiving, from a second videogame client device, a second transaction record reflecting a second set of events associated with the interactive videogame session, wherein the second transaction record is cryptographically signed by a second private cryptographic key associated with the second videogame client device; and validating the first transaction record based on the second transaction record.

Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing at least one program and a method for providing a platform that facilitates communication between a messaging application and a web-based gaming application; receiving, via the platform, a request from the web-based gaming application to execute a reward activity; determining, by the messaging application, that the request satisfies a reward activity criterion; generating the reward activity on the messaging application in response to receiving the request; and communicating, via the platform, a status of the reward activity from the messaging application to the web-based gaming application.

A multiplayer software “wrapper” is provided around a conventional single-player modality game. The wrapper allows multiple players, each with their own player device, to share a common multiplayer game session. The single player game is hosted on a game server and is coded to support only a single player device. The wrapper provides a multiplayer interface to the single-player game in a way that does not require any modification of the underlying game code or game server architecture. A centralized and automated gameplay system sits between, on the one hand, the multiple player devices and, on the other hand, the gameplay server hosting the single player. The gameplay system collects game instructions from multiple player devices and determines single-player inputs to the game based on the game instructions from the multiple player devices.

A non-transitory computer-readable storage medium storing a program configured to cause a terminal device to execute a game in communication with a server device, the program includes: a first storing step of receiving from the server device at least one token generated and stored in the server device to store the token in a terminal storage unit; a transmitting step of transmitting to the server device information-to-be-transmitted including an updating instruction of game data of a user and encrypted information obtained by encrypting information-to-be-encrypted at least including the token; and a deleting step of deleting the token stored in the terminal storage unit, wherein the updating instruction includes a first instruction to update the game data stored in the server device when the token extracted by decrypting the encrypted information and the token stored in the server device are matched.

A computer that performs authentication is described. During operation, the computer may receive an authentication request associated with an individual playing a video game. In response to the authentication request, the computer may obtain game information associated with current play of the video game by the individual and second game information associated with one or more prior instances of the individual playing the video game. Then, the computer may determine the authentication of the individual based at least in part on the game information and the second game information. Next, the computer may selectively allow the individual to continue to play the video game based at least in part on the authentication.

A plurality of game apparatuses function as a master, a client, and an audience. The master and the client register each other by performing therebetween an authentication process. The authentication process is not performed between the master and the audience. The audience receives a beacon from the master and registers the master in an own apparatus while the audience is not registered in the master. The master and the client execute a predetermined program, exchanging data by communicating with each other. The audience receives the data exchanged between the master and the client, and executes the predetermined program using the received data, thereby watches a game which is progressed between the master and the client, as a spectator.

A method and system tracks, analyzes or sorts behaviors of user or players across a network to draw correlations from, or characterizations of, those user or players and identifies similarly characterized or mutually complementary user or players. For example, the method automatically obtains player data regarding interactions by each of multiple players with a multiplayer electronic game via each player's corresponding data processing device connected via the network. The method can then sort, classify or suggest additional activities, games, groups, or other different activities or actions for the players.

Systems and methods for sharing user inventory information to initiate peer-to-peer exchanges of digital assets that are usable within an online gaming platform are disclosed. Exemplary implementations may: receive a sharing request for information regarding a first user inventory; access a blockchain to obtain asset information; transfer the asset information in response to the sharing request; receive an offer request for the transfer of ownership of a first digital asset from a first user to a second user; if the offer according to the offer request is accepted, receive a transfer request and transfer the ownership of the first digital asset as requested.
