The document discusses digital identity and biometrics. It notes that while digital communication is now common, digital identity can be vulnerable to fraud like password theft or breaking encryption keys. Biometrics provide a more secure method of verifying identity by using unique human traits. The document then describes dynamic signature verification, which analyzes characteristics of physical signatures to authenticate identity. It presents AutDSig as a solution that combines biometrics with digital certificates to uniquely verify identity when signing documents.

1. AutDSig
®

2. We live in the era of instant communication based on the
mobility. Consequently, more exposed.

3. In the Cyberspace the human being is represented through
its Digital Identity ...

4. THE DIGITAL IDENTITY
Covers a set of updated information,
organized and encoded (encrypted) by
electronic means concerning individuals
and corporations.

5. .. But ... it is still possible fraud. DIGITAL CRIME
1. Breaking the encryption key
2. Password Theft

6. LAW AND TECHNOLOGY
Basically regards the survey, analysis and resolution of
legal issues raised by the application of Computer
Tchnology
• Computerization of legal acts, signature, proof,
payments, eletronic contracts;

7. Lagged level of security of
Digital Certificate
How to troubleshoot?

8. Presumption that the person signed. Relative or Absolute?
In Brazil, the law MP 2200-2 states that any digital document is
legally valid if certified by ICP-Brazil, Brazilian official's public key.
The whole structure of the Legal Personality in this set
passwords and encryption keys. There are no unique traits of
the author. Thus, ICP-Brazil determining the presumption is
relative, while the AutDsig the presumption is absolute.
No one can go through you

9. Biometrics: personality traits
"Single measurable characteristic or a trait of human
beings that automatically recognizes and verifies your
identity."

10. Three steps of biometric security
High: something
only YOU and
your DOING
Average: something that you
KNOW
Ex: password to access computer
Low: something that you HAVE
Ex: ID card with photo

11. Development of biometric systems
It takes physical and behavioral characteristics for recognition,
namely:
Uniqueness: as unique as possible
Universality: there are many people as possible in
Measurability: can be measured with technical instruments simple
User friendly: they are easy and comfortable be
measured

12. Signature: convergence between law and technology
Provides the undeniable proof that a message came
from the sender. It can be seen through the following
properties:
1. Authenticity
2. Integrity
3. Non-repudiation (Irreversible)

13. Biometric signature:
Dynamic Signature Verification (DSV)
Some features can be extracted and measured by DSV:
1. The form
2. The time it takes to sign
3. The angle at which the pen is held
4. Speed ​and acceleration signature
5. The pressure is safe when the pen
6. The number of times that the pen is
raised paper

14. Basic process of the DSV
1. Capture: the data is captured through the signing of a
pen or sensitive surface, or both

15. Basic process of the DSV
2. Extraction: the unique characteristics of the signature is
extracted, encoded by a biometric device and stored as a
template

16. Basic process of the DSV
3. Comparison: biometry signature are
verified.

17. Advantages of DSV:
1. Signature of the most accepted ways to identity validation.
2. Inability to transfer responsibility

18. AutDSig® as a solution
It is important to understand that there are products on the market
that use a digital signature or digital certificate, or both. In either case
the security is provided by a digital password.
We are different.
We offer the product that combines unique characteristics of the
individual to Certificates Public or Private, ensuring their safety in a
unique way. With asymmetric key itself, our software is ready to use
any biometric product on the market, adapting to the needs of each
client.

19. AutDSig® as a solution
What we value:
1. Flexibility: we tailor the use of several biometrics;
2. Scalability: one or more people, everyone can use;
3. Operating platform independence: we are everywhere;
(Windows, Linux, Unix and MacOS)
4. Regardless of any graphical interface : always the best usability
