摘要： Disclosed are a method and apparatus for masking a privacy area of an image. The method for masking a privacy area of an image includes: detecting a privacy area required to be protected in an image; and performing masking on the image. An important area (a face area of a person, a number plate area of a vehicle, a window area of a house, etc.) detected from an image inputted through a CCTV camera can be effectively and easily encrypted, scrambled, decoded, and descrambled. Also, the position of the important area detected before or after the important area is scrambled can be maintained to be consistent without having to use a metadata file. In addition, a scrambling algorithm of the same key value can be applicable regardless of the size of the important area. As a result, the system efficiency can be enhanced by effectively protecting personal information compared with a CCTV-based video security system.

摘要： Provided are a key establishment method and system using commutative linear functions. In the method, a server defines a set of linear functions that use elements of a first finite field as coefficients and satisfy a commutative rule, selects a first linear function from the set, and selects a predetermined element from a second finite field. Next, the server selects a second linear function corresponding to each of nodes from the set, generates a predetermined combination function based on the first and second linear functions, generates a value of the second linear function using the selected element as a factor, and transmits the combination function and the value of the second linear function to a corresponding node. Each node receives the value of the second linear function from a server, exchanges the received values with the other nodes, computes a value using the exchanged value as a factor of the combination function, and establishes the computed value as a shared key between the nodes. Therefore, each node can perform key establishment with a small amount of computation and low memory consumption, while guaranteeing end-to-end security.
摘要翻译：提供了一种使用交换线性函数的关键建立方法和系统。在该方法中，服务器定义一组线性函数，其使用第一有限域的元素作为系数并满足可交换规则，从集合中选择第一线性函数，并从第二有限域中选择预定元素。接下来，服务器从集合中选择对应于每个节点的第二线性函数，基于第一和第二线性函数生成预定的组合函数，使用所选择的元素作为因子生成第二线性函数的值，并且发送组合函数和第二个线性函数的值对应一个节点。每个节点从服务器接收第二线性函数的值，与其他节点交换接收的值，使用交换的值作为组合函数的因子计算值，并将计算值建立为节点之间的共享密钥。因此，每个节点可以执行少量计算和低内存消耗的密钥建立，同时保证端到端的安全性。

摘要： There is provided an anonymous service method of providing local linkability. The anonymous service method providing local linkability according to exemplary embodiments of the invention, an anonymous authentication operation based on a short group signature is performed, for which the concept of a local linkability is introduced to secure linkability within the same service domain. Namely, in the interior of a service provider, a virtual index having a fixed value is calculated for each service user, and in this case, although a plurality of service providers collude with each other, they cannot calculate a virtual index having the same value, whereby the linkability can be secured within the same service domain but not within the interiors of different service domains.
