Description

"AUTHENTICATION SYSTEM BASED ON MULTIMODAL BIOMETRICS"
FIELD OF THE INVENTION
The invention refers to a distributed authentication system using temporal synchronism and automatic adaptation of biometrical features. The invention is applied in electronic systems equipped with the function of physical access controlling, information access controlling, and/or services access controlling.
More particularly, the present invention consists of a biometrics system based not only in the cross-verification of different biometrical features, but also in its temporal synchronism to proceed with the authentication of the user in systems that requires some type of access control. In addition, the distributed authentication system allows the authentication of the user in a noninvasive manner and in some cases without interaction. Finally, since the system of the invention is provided with automatic adaptation, the system allows the automatic update of isolated changes of the biometrical features, if other features are sufficient to authenticate the user.
BACKGROUND OF THE INVENTION
The first methods and devices used for authentication were based on physical solutions, like keys or documents, or based on solution knowledge, like passwords or personal information. These methods and devices are until today applied but on the other hand they are technically overshot.
Aiming to reduce the inefficacy, the susceptibility to frauds and the discomfort of said methods and devices, isolated biometrical features to proceed with the authentication, as of digital signature and fingerprint, started to be used. Biometrics, as this use of biometrical features is called, presents two main advantages when compared with the other authentication methods: the control parameters are intrinsic to the individual, thus being impossible that the individual lose them somewhere, and the fact that each individual is unique, thus making difficult the fraud based on someone's biometrical features.
Some of the methods and devices of the state of the art store biometrical information in cards, as disclosed in publications WO 2004/025545, WO 2003/040996, and WO 2000/00923. The common deficiencies to all of the current authentication systems that are based on biometrics consist of the following facts: they are, in general, invasive, i.e. they need physical contact; they are, in general, interactive, i.e. user needs to undergo an authentication process; they are also susceptible to frauds; and they are not adaptive so they might not work well when little natural variations in controlled biometrical features occur.
Multimodal biometrics consists of the simultaneous use of several biometrical different features, aiming to diminish the susceptibly to frauds. Even thought, the cross confirmation of these different features makes the fraud difficult, but not impossible. A multimodal authentication system based on recognizing face and recognizing speech, for example, might be fraud with the use of a picture and a record. Several multimodal biometrics systems using a great variety of biometrical features (such as facial image, fingerprints, DNA sequencing, signature, dental arch, print of the palm of the hand, retina, iris, facial shape, hand shape, finger shape, handwriting and typing dynamics, arrangement of blood vessels) are known in the state of the art. Some of them are disclosed in US 2003031348, US 200300531 1 , US 2002147691 , US 2002152034, WO 2002/29741 , WO 2002/201328, and US 2001017584, but all of them present the above-mentioned deficiencies.
DESCRIPTION OF THE INVENTION Thus, aiming to overcome the deficiencies of biometrical authentication systems of the state of the art, a new, non-invasive, adaptive, and less susceptible to frauds authentication system according to the present invention was created. According to the present invention, a multimodal biometrics method is based on the integration of the authentication results of the different biometrical features, and based on validating theses features through the verification of the temporal synchronism between diverse features. Thus, for example, recognizing face and voice can be validated through the verification of the temporal synchronism between theses features. This is possible using lip reading, for example.
The present invention also employs a method of multimodal biometrics with automatic adaptation of the biometrical features that allows the automatic detection adaptation of the system to isolated variations of the biometrical features, such as hoarseness, when one of the biometrical features is the voice, or a change in the haircut, when one of the biometrical features is the face, for example.
The present invention also foresees a distributed authentication system that diminishes the invasiveness of the authentication system.
BRIEF DESCRIPTION OF THE DRAWING
The present invention will be described herein with relation to a particular embodiment represented in attached figure, included in this specification for illustrative purposes only. Such figure is schematic, and its dimension and/or proportion may not correspond to the reality since it illustrates the present invention didactically, without imposing any limitations other than those contained in the attached claims, wherein:
- Figure 1 is a schematic block diagram that illustrates the functioning of the authentication system according to the invention. DESCRIPTION OF PARTICULAR EMBODIMENTS
Figure 1 shows an example of the system based on two biometrical features, wherein the use of more than one feature is carried out.
The different biometrical sensors (1 ) and (2) used in the system are distributed in the environment according to a criteria that depends on the nature of the biometrical features measured. Data raised by sensors (1 ), (2) are subjected to a temporal synchronism sensor (3) appropriated to the measurement, to minimize the possibility of fraud. The information captured by the three sensors (1), (2), and (3) undergoes then through a decision device (4), responsible for the user's authentication through a consultation to a database (5) with the object to eliminate the invasiveness of the system. The result of the decision device (4) is used by the access control device (6) that allows or not the physical access to the information and/or to services. This same result of the decision device (4) re-feeds the system through the adaptation device (7), which can actuate in the database (5) updating the user's data, or in the sensors (1 ) and (2) in case there is need of more information to the decision device (4).
According to the present invention, different biometrical features can be validated due to their temporal synchronism, thus making the authentication more solid, more trustworthy, and less susceptible to frauds. In addition, the present invention can provide greater comfort, once the biometrical reference information are stored in a database, thus not being necessary the user to carry any type of device or card and eliminating the invasiveness of the system. Finally, the system according to the present invention reduces the susceptibility to failures, once the system adapts the database when it detects a natural variation of any biometrical feature, such as hoarseness, a change in the haircut or other natural variation of the biometrical features due to age, for example. Besides that, the set of biometrical features to be used can be chosen due to the nature of the environment at which the system is used, making it more adapted to every situation of different use. In every case, only one biometrical stipulation can be used to assure the temporal synchronism of the other ones. The present invention has been described in relation to a particular embodiment. Those skilled in the art may develop a wide variation of structural details without, however, deviating from the principles of the present invention. Therefore, the attached claims shall be interpreted as covering all equivalents that fit into the scope and character of the present invention.
