چکیده (انگلیسی):

A new approach for measuring security is proposed. A lightweight model to quantify the security level perception has been developed. For this purpose, the paper defines a function to systematically represent how security-insecurity is perceived. The function defined shares several characteristics with a reliability function. The model is based on the characteristics of perceived security level over time and how it is related to human perception. The security level function is parameterized based on a minimal quantity of known data. The value obtained is an indicator for quantifying the security level and predict how it will change over time. This approach permits to implement countermeasures and strategies in advance. The proposal is useful in any security context and mobile technologies are key in order to make the model useful.
