Abstract: A system and a method are provided for facilitating an account protection check through blockchain. The system and the method allow a service provider to utilize blockchain technology to validate the access request to various accounts. A public key and a private key are generated and recorded by a blockchain ledger that are used to access the accounts. A third-party server of a service provider requests a token from the system before the authentication process. If the credential set is in a locked status or unlocked status, at least one remote server of the system respectively relays an invalidation token or a validation token to the third-party server. If the invalidation token is relayed to the third-party server, the service provider does not go through the authentication process. If the validation token is relayed to the third-party server, the service provider proceeds with the authentication process as standard procedure.

Abstract: A system and a method are provided for facilitating an account protection check for the security of sets of credentials. The system and method enable the use of an access control mechanism to regulate the changes to the lock status of the sets of credentials. A third-party server of a service provider requests a token from the system before the authentication process. The access control mechanism also approves or denies the request before the authentication process. If the credential set is in a locked status or unlocked status, at least one remote server of the system respectively relays an invalidation token or a validation token to the third-party server. If the invalidation token is relayed to the third-party server, the service provider does not go through the authentication process. If the validation token is relayed to the third-party server, the service provider proceeds with the authentication process as standard procedure.

Abstract: A system and a method are provided for facilitating an account protection check for the security of sets of credentials. The system and method allow a service provider to automatically lock a credential set of at least one user account if fraudulent activity is detected. A third-party server of a service provider requests a token from the system before the authentication process. User metadata is analyzed to detect potentially fraudulent activity from the user account. If the credential set is in a locked status or unlocked status, at least one remote server of the system respectively relays an invalidation token or a validation token to the third-party server. If the invalidation token is relayed to the third-party server, the service provider does not go through the authentication process. If the validation token is relayed to the third-party server, the service provider proceeds with the authentication process as standard procedure.

Abstract: An infant drinking cup is described. The infant drinking cup is a first color when at room temperature. When the cup is filled with a cold beverage, the portion of the cup below the fill line changes to a second color. When handled by an infant, those areas below the fill line in contact with the infant's warm hands change color back to the first color. The process is fully reversible, such that the infant drinking cup can change from the cold color to the warm color, and vice versa, repeatedly.

Abstract: The invention discloses an amusement projectile characterized in a first embodiment by a football shape which is thrown by a user and which comprises electronics therein to measure and display the distance traveled by the thrown ball to the point of impact with the ground or to another user. Using an accelerometer in cooperation with a microprocessing board disposed within the ball, the distance traveled is determined by measuring the initial velocity and the time recorded during the flight of the ball based upon changes in the acceleration of the ball, and an inset liquid crystal display screen mounted on the football is used to display the distance as well as time of flight and a nondimensional thrust value. A toggle button is used to alternately display the "flight characteristics," which are distinguished by the position of a decimal in the three digit display.
