Yuri Gurevich made many varied and deep contributions to logic for computer science. Logic provides also the theoretical foundation of database systems. Hence, it is almost unavoidable that Gurevich made some great contributions to database theory. We discuss some of these contributions, and, along the way, present some personal anecdotes connected to Yuri and the author. We also describe the h...

Due to the trend that more and more web services, such as Google, Facebook, and many auction websites, require users to open their new accounts or to login to their accounts through cell-phone-verification, cell-phone-verification has become an important function of cellular phones. However, our research shows that cell-phone-verification is not always reliable. This study proposes a new attack...

A long time ago, Yuri Gurevich made precise the problem of whether there is a logic capturing polynomial-time on arbitrary finite structures, and conjectured that no such logic exists. This conjecture is still open. Nevertheless, together with Andreas Blass and Saharon Shelah, he has also proposed what still seems to be the most promising candidate for a logic for polynomial time, namely Choice...
