Algorithms are now widely used in all areas of social life, building a new social picture and reality. As a technology based on big data modelling and analysis, algorithms are embedded in all aspects of information production and distribution by means of technology, and become an important force in the construction of information environment. Under the algorithmic logic of information dissemination, the visible and invisible are in fact influenced by the algorithm as an authoritative mediator and mediator. From Daniel Dayan's 'visibility' perspective, this paper examines the risks posed by algorithms in three areas: the risk of passive disclosure of personal privacy, the use and control of personal data by profit-seeking algorithms, and the polarisation of information cocoons and circles. The information security risk brought by algorithms is attempted to be tackled and improved from several aspects, such as constructing a 'trinity' information security strategy system; adhering to the mainstream value orientation and highlighting the rational balance of “tool-value” of algorithms; and bringing into play multiple mechanisms together with effects.
