Signature databases are structured sets of collected signatures from a group of individuals that are used either for evaluation of recognition algorithms or as part of an operational system.

Signature databases for evaluation purposes are, in general, collections of signatures acquired using a digitizing device such as a pen tablet or a touch screen. Publicly available databases allow a fair performance comparison of signature recognition algorithms proposed by independent entities. Moreover, signature databases play a central role in public performance evaluations, which compare different recognition algorithms by using a common experimental framework. This type of databases is covered in this entry.

On the other hand, signature databases can also be a module of a verification or identification system. They store signature data and other personal information of the enrolled users. This signature database is used ...
