Abstract: [Object] To provide an information processing apparatus and a control method that can differentiate between an area that can be visually recognized only by a specified user and an area that can be visually recognized by all users on an information presentation surface that is simultaneously viewed by a plurality of people. [Solution] Provided is an information processing apparatus, including: a line-of-sight detection unit configured to detect lines of sight of a plurality of users with respect to presentation information; and an area determination unit configured to determine, on the basis of the detected lines of sight of the plurality of users, a shared area that is visually recognized by the plurality of users to share information and a confidential area that is not visually recognized by another user to keep information of each user confidential.

Abstract: An authentication device includes circuitry that holds L (L≧2) secret keys si (i=1 to L) and L public keys yi that satisfy yi=F(si) with respect to a set F of multivariate polynomials of n-th order (n≧2). The circuitry also performs with a verifier, an interactive protocol for proving knowledge of (L−1) secret keys si that satisfy yi=F(si). The circuitry receives L challenges from the verifier, arbitrarily selects (L−1) challenges from the L challenges received. The circuitry also generates, by using the secret keys si, (L−1) responses respectively for the (L−1) challenges selected, and transmits the (L−1) responses generated.
Abstract translation: 认证装置包括相对于n阶多项多项式的集合F保持满足yi = F（si）的L（L≥2）个秘密密钥si（i = 1〜L）和L个公钥yi的电路 （n≥2）。 电路还与验证器一起执行交互协议，用于证明满足yi = F（si）的（L-1）秘密密钥si的知识。 电路从验证者接收到L个挑战，从接收到的L挑战中任意选择（L-1）挑战。 电路还通过分别使用所选择的（L-1）挑战的秘密密钥si，（L-1）响应来生成并发送生成的（L-1）个应答。
