Secure sketches are useful in extending cryptographic schemes to biometric data since they allow recovery of fuzzy secrets under inevitable noise. In practice, secrets derived from biometric data are seldom used alone, but typically employed in a multi-factor or a multimodality setting where multiple secrets with different roles and limitations are used together. To handle multiple secrets, we ...

Filippo Brunelleschi (1377-1446), a Florentine architect and Renaissance polymath, not only invented mirror that allowed artists draughtspersons to capture linear perspective, he was also the first beneficiary of modern patent. Governments grant patents as time-limited, monopoly exploitation rights over inventions in exchange for full disclosure details invention. On expiry monopoly, anyone can...

We analyze some specific aspects concerning conditional orderings and relations among them. To this purpose we define a suitable concept of reversed conditional ordering and prove some related results. In particular we aim to compare the univariate stochastic orderings ≤st, ≤hr, and ≤lr in terms of differences among different notions of conditional orderings. Some applications of our result to ...

In the change of the orientation one has to reverse the sequence (the operation introduced in [7]) and to change the second restriction one has to rotate the sequence (the operation introduced in [26]). The goal of the paper is to prove, mostly simple, facts about the relationship between properties and attributes of the finite sequence and its rotation (similar results about reversing had been...
