  • Publication number: 20220200799
    Abstract: A method, computer program, and computer system is provided for encrypting data or information represented by bits, numbers, used to encode images, text, or audio. For the case of an RGB image encryption applications, the data may be separated into its constituent channels before encryption. In addition to the standard encryption keys, another encryption isokey is generated based on an isounit using an algebraic isofield having a multiplicative identity value different than the number one. On the sender side, each of the channels is encrypted using the standard keys and the generated isokey. On the receiver side, each encrypted channel is decrypted before combining them to obtain the recovered RGB image. In addition to images, the cryptographic algorithm can also be used the encrypt data related to text, audio, and other file types.

    Abstract: A system is configured to collect information regarding a user's sleep and to graphically convey sleep factors based on the information to a user. The system can include a control circuit and a sensor that work together configured to generate a first sleep factor. The first sleep factor is associated with the user's sleep episode. A database is communicatively coupled to the control circuit and stores a graphical representation of the user and a second sleep factor, which is defined by the user. The control circuit uses the first and second sleep factors to determine a sleep episode score. Optionally, the control circuit effects conveying the determined sleep episode score to the user via the graphical representation of the user.
