Safelayer took part in the 11th edition of the Workshop on Interoperable Social Multimedia Applications (WISMA), organized by the Distributed Multimedia Applications Group (DMAG) of the UPC, presenting the article "A trustworthy and privacy-enhancing registration process for social network services".
With the proliferation of social networks on the Internet, and their massive capture of users, trust and privacy issues have emerged:
- The fact that users enter their own data in their profiles on social networks gives rise to a problem of information quality and trust as this information does not necessarily have to be true. Social networks could provide greater trust to their users if the data included was verified beforehand.
- Social networks represent a problem for privacy as some of the details required for the registration processes are not necessary for the service provided by the social network.
Considering that many of the users of social networks are minors, these two factors become even more important. To avoid an improper use of these applications in the case of minors, it is essential that the social network can verify that its users are over, for example, 14 years of age, and that users can prove this without revealing their exact date of birth.
In the article, Safelayer and DMAG present a new registration process for social networks that provides greater trust to the data while also giving greater privacy to users. This is achieved through a combination of digital certificates-which are an important source of trusted data, and tarjetas de información-which provide users with control over what data they want to reveal.
This solution is implemented via the two prototypes:
- Interidy Identity Provider,for generating information cards from the data contained in digital certificates, and
- PKI Trust Center, which provides a trust rating for each certification authority and, as a result, for its certificates.
