The deployment of security measures can lead in many occasions to an infringement of users' privacy. Indeed, nowadays we have many examples about surveillance programs or personal data breaches in online service providers. In order to avoid the latter problem, we need to establish security measures that do not involve a violation of privacy rights. In this communication we discuss the main challenges when conciliating information security and users' privacy.
As it is the case in most Spanish universities, at the Colleges of Engineering where we teach we have begun the implementation of the new qualification system that has been proposed in the Bologna agreement. During the academic year 2010/2011 we have used Moodle, the learning online platform, as an important part of the subjects we teach, particularly Linear Algebra. This paper presents the experience resulting of the interaction of undergraduate students with the new teaching-learning system, using the algebraic editor WIRIS implemented in the Moodle platform, together with other specialized tools, like the computational knowledge engine WolframAlpha or the computer programs Microsoft Mathematics and GeoGebra, in order to support and improve lessons, taking into account that computers help students to interact with teachers and with other classmates and to acquire knowledge using these learning tools.
