Usable presentation of secure pseudonyms

Content Provider ACM Digital Library
Author Pfitzmann, Andreas Borcea-Pfitzmann, Katrin Franz, Elke
Abstract Privacy-Enhancing Identity Management (PIM) enables us-ers to control which personal information they provide to their communication partner(s) by partitioning their personal information into partial identities for themselves. Since partial identities must not be linkable, they cannot share a global name. Therefore, pseudonyms are used as identifiers.We discuss in this paper that besides the frequency of their use also the (re)presentation of pseudonyms influences the achievable privacy. Particularly, we point out that conflicting requirements on privacy and usability cannot be sufficiently considered by a single type of representation of pseudonyms. Hence, a PIM system should generate digital pseudonyms which are used for communication, while users assign local mnemonics to these pseudonyms in order to simplify their use. We discuss possible solutions for the support of mnemonics and, thereby, propose some improvements to privacy-enhancing identity management tools.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
