Where did the word technology come from?
the word technology comes from GREEK word Techne means "ART" and Logy means "to talk about something". The specific methods, materials and devices used to solve problem is called technology.
Explain three different methods in java?
There are three different methods /functions in java are there : 1)computational methods.2)manipulative methods.3)procedural methods.
Is it possible to override overloaded methods why?
Yes. Overloaded methods are also Java methods and all Java methods can be overridden.
Can instance methods replace class methods in programming?
No. never. An instance method cannot replace a class method because: Instance Methods - are normal methods that are linked to a class object instance Class Methods - are static methods that are not linked to any class object. These methods are not interchangeable and will create too many issues if we try to use one in place of the other.
Where is pawsitive methods?
Pawsitive Methods is located in California, USA.
What is biometric authentication methods?
Biometric authentication - is using something like a fingerprint scanner to verify a persons identity. These devices are used in high-security areas such as a power stations control room, so that only those people who are authorised to work there actually get into the building.
What is an advantage of biometric devices?
Biometric devices provide a high level of security compared to traditional methods like passwords or PINs because they are unique to each individual. They are also convenient to use as they do not require the user to remember or carry any additional credentials. Additionally, biometric authentication is difficult to forge or replicate, adding an extra layer of protection against fraud.
Why do biometric scanning devices uses fingerprints and iris scanners?
Biometric scanning devices use fingerprints and iris scanners because they are unique to each individual and difficult to replicate. Fingerprints have been widely used for identification due to their distinct patterns, while iris scanners offer high levels of accuracy as the patterns in the iris are highly distinctive and stable over time. Combining these two methods enhances the security and reliability of the biometric authentication process.
What is biometric passwords?
Biometric passwords are authentication methods that use unique biological traits such as fingerprints, facial recognition, or iris scans to verify a person's identity. These biometric data points are difficult to fake or duplicate, making them a secure form of password authentication.
What is true about biometrics as an authentication method?
computer scientists are always trying to improve biometric authentication methods
What are methods of computer security?
Access Control Systems. Authentication. Multi-factor authentication Authorization. Firewalls and Internet Security. Intrusion prevention system. Intrusion detection system.
How disadvantages of biometrics can overcome?
Some disadvantages of biometrics, such as privacy concerns and potential security breaches, can be overcome through implementing strong encryption methods to protect biometric data, using multifactor authentication to enhance security, and providing transparency to users about how their biometric data is being used and stored. Additionally, educating users about the benefits and risks of biometric technology can help build trust and acceptance of these systems.
What is biometric identification devices?
Biometric identification devices are security systems that use unique physical or behavioral characteristics, such as fingerprints, iris patterns, or facial recognition, to authenticate an individual's identity. These devices provide a more secure and convenient way to access sensitive information or restricted areas compared to traditional methods like passwords or ID cards.
What is a A type of attack where an intruder is able to forge a biometric sample?
Methods used to successfully forge biometric input have included using a jelly copy of a finger with the fingerprint embedded on it and using a photograph of an individual in place of their face for a facial scan. The better biometric devices will incorporate methods to prevent these types of methods from succeeding, but both these two methods and others have been demonstrated as still working on some biometric authentication devices still on the market. There is also the potential problem of "splicing". Some formats for smart cards sign each piece of information separately, so an attacker can steal the legitimate signed identity of another user and splice it into his own biometric information. To combat this, better smart cards sign the entire set of data including both the user identity and their biometric information.
What is a type of attack where an intruder is able to forge a biometric sample?
A type of attack where an intruder is able to forge a biometric sample is known as a spoofing attack. In this type of attack, the intruder uses a fake biometric sample to trick the system into granting unauthorized access. Spoofing attacks can involve creating replicas of fingerprints, iris patterns, or facial features to bypass biometric security measures.
What is a reinforced authentication?
Reinforced authentication refers to enhanced security measures implemented to verify a user's identity beyond standard methods, such as passwords. This can include multi-factor authentication (MFA), which requires users to provide additional verification, such as a text message code or biometric data like fingerprints. By adding these layers, reinforced authentication significantly reduces the risk of unauthorized access and protects sensitive information.
Is a biometric device a input or output device?
Most biometric devices would be input devices although they may also utilize storage devices and output devices in their functioning. A biometric device usually takes in biometric information about a person and compares it to information stored in a database - much like username/password methods of authentication compare the username and password to the stored information for a user. Fingerprint scanners, read the fingerprint, convert it to a data stream and then compare it to the stored data previously recorded for the individual, retinal scanners read information about the retinal patterns of a user, convert it to data and compare it to stored data, etc. Note that biometric devices must rely on a storage device, but usually the storage device is not part of the biometric device. Instances of OUTPUT associated with a biometric device might be a signal to open a door or trigger an alarm, but again, the output usually comes from another device that the biometric device is connected to.
