Users must recall the textual strings selected during registration to pass authentication. However, there are some serious problems with text passwords---recollection and security. Hence, various graphical-password authentication systems have been proposed to solve the problems of text passwords. Previous studies indicate that humans are better at recognizing and recalling images than texts. In 2005, Wiedenbeck et al. proposed PassPoints in which a password consists of a sequence of click-points (5 to 8) that a user chooses on an image. In the paper, we proposed an alternative system in which users can memorize fewer points while providing more security than PassPoints. Based on the idea of using an extremely large image as the password space, we propose a novel world map based graphical-password authentication system called PassMap in which a password consists of a sequence of 2 click-points that a user selects on an large world map. We also conducted a user study for evaluation. The result shows that the passwords of PassMap are easy to memorize for humans and PassMap is friendly to use in practice. Furthermore, PassMap provides higher entropy than PassPoints and also increases the cost of attacks.","PeriodicalId":72308,"journal":{"name":"Asia CCS '22 : proceedings of the 2022 ACM Asia Conference on Computer and Communications Security : May 30-June 3, 2022, Nagasaki, Japan.

To use these services, developers must bundle third-party, binary-only libraries into their applications. In this model, applications and their advertising libraries share permissions. Advertising-supported applications must request multiple privacy-sensitive permissions on behalf of their advertising libraries, and advertising libraries receive access to all of their host applications' other permissions. We conducted a study of the Android Market and found that 49% of Android applications contain at least one advertising library, and these libraries overprivilege 46% of advertising-supported applications. Further, we find that 56% of the applications with advertisements that request location (34% of all applications) do so only because of advertisements. Such pervasive overprivileging is a threat to user privacy. We introduce AdDroid, a privilege separated advertising framework for the Android platform. AdDroid introduces a new advertising API and corresponding advertising permissions for the Android platform. This enables AdDroid to separate privileged advertising functionality from host applications, allowing applications to show advertisements without requesting privacy-sensitive permissions.","PeriodicalId":72308,"journal":{"name":"Asia CCS '22 : proceedings of the 2022 ACM Asia Conference on Computer and Communications Security : May 30-June 3, 2022, Nagasaki, Japan.

However, almost all known solutions solely aim at achieving sender or requestor anonymity in DHT queries. In many application scenarios, it is crucial that the queried key remains secret from intermediate peers that (help to) route the queries towards their destinations. In this paper, we satisfy this requirement by presenting an approach for providing privacy for the keys in DHT queries.\u0000 We use the concept of oblivious transfer (OT) in communication over DHTs to preserve query privacy without compromising spam resistance. Although our OT-based approach can work over any DHT, we concentrate on robust DHTs that can tolerate Byzantine faults and resist spam. We choose the best-known robust DHT construction, and employ an efficient OT protocol well-suited for achieving our goal of obtaining query privacy over robust DHTs. Finally, we compare the performance of our privacy-preserving protocols with their more privacy-invasive counterparts. We observe that there is no increase in the message complexity and only a small overhead in the computational complexity.","PeriodicalId":72308,"journal":{"name":"Asia CCS '22 : proceedings of the 2022 ACM Asia Conference on Computer and Communications Security : May 30-June 3, 2022, Nagasaki, Japan.
