password keystrokes to determine the probability that the person logging in is the person he/she claims to be. We now have a conditional probability that this is the real person that logged in given the prior probability of their claim to identity based on their privacy security history (see Table 1).

The problem of finding the probability of keystroke sequence S can be viewed as how well a given HMM λ=(A,η,π) would score on S. We use the Forward Algorithm [8] to calculate the probability of an m long keystroke sequence S with n-graph G, and n-graph durations GD. The state probabilities α's of each state can be computed by first

Gaussian Probability Density is used as a function for calculating the similarity of feature (keystroke duration). The organization of this paper is as follows: Section 2 discusses the various researches related to biometric authentication, as well as keystroke base authentication.

Suppose the probabilities of a finite sequence of events is given by the probability distribution P= {p1...pn}, but somehow we mistakenly assumed it to be Q= {q1...qn}. According to this erroneous assumption, our uncertainty about the jth event, or equivalently, the amount of information provided after observing the jth event.

- Biometric identification and authentication depends on unique biological attributes, such as a fingerprint, an iris, a face or even a heartbeat. These attributes are much more difficult for hackers and criminals to exploit because they’re unique to each individual.

### Biometric?

Biometric functionality. Many different aspects of human physiology, chemistry or behavior can be used for biometric authentication.The selection of a particular biometric for use in a specific application involves a weighting of several factors. Jain et al. (1999) identified seven such factors to be used when assessing the suitability of any trait for use in biometric authentication.

### Biometric identification or biometric authentication?

One of the main differences between biometric identification and biometric authentication is that in identification there is a relatively simple match of a ‘live’ biometric with a stored biometric template. For authentication, the biometric is used as part of a biometric protocol that includes the use of standardized authentication processes including identity proofing, cryptographic protocols, identity assertion, and credential lifecycle management.
