Cryptography is one of widely used technique of secret writing which is the term used for data and information security and protects that information from various attacks. Cryptography is the process of converting a known text or plaintext into a human unreadable format called cipher text by encoding the original message using some encoding technique. Security is concerned with the protection of the network and data transmission over the network. Data Security is the most essential aspect of secure data transmission over the network. But to achieve complete data security is a challenging issue of data communication.
User ID and password are the mandatory login credentials to access your account. In addition to them, Transaction password is quite essential to transfer the money. Both the login password and transaction password are the confidential. Along with both these passwords you would receive a verification code (one time password) to the registered mobile number to ensure that you are the person who is accessing the account. All the three passwords are confidential to keep your account and money secured.
Passwords are the frontline of protection of user accounts. Password policies are in place for a variety of reasons. These policies are to establish a standard for strong password creation, the protection of the passwords, and the frequency at which it is changed. The Virtual Private Network (VPN) extends a private network across a public network like the internet. It enables users to send and receive data across shared or public networks.
This are all unique characteristics for each and every human being so we can use this characteristics as authentication password. Biometrics is a computer science provide access control so only authenticate person is able to access the data. The term Biometrics is the combination of two words that are BIO means “life” and METRICS means “measure”. So in this paper we think that “can we use wrist pulses as a password?” Yes ,we can use wrist pulses as a authentication & to maintain confidentiality of data or to secure important data. Biometrics System Biometrics is a technology use to protect or maintain confidentiality and integrity of the data.
This model is based on assigning security labels called security clearances to all object and users according to the specified classification. Thus, it enables a user read the objects which have the same label or smaller. For example, if considering the following classification of security levels: Unclassified – Confidential – Secret – Top Secret (each level dominates the previous), the user possessing a label “Secret” is not able to access the information labeled as “Top Secret” . The information flow from dominating level to lower level is regulated by the “Read down” and “Write up” principles. The integrity of information is also regulated by the two principles “Read up” and “Write down”
Setting file permissions is a form of DAC because it is the owner’s discretion. Configuring as many security layers as the user can will ensure the server will stay secure. Not all OS are 100% secure, but they can be configured to make it very hard for a hacker to
To avoid problems of identification and authentication, we need strong authentication over the system. PKG has the main role in authentication because PKG is the trusted third party between users and data owners in the system. PKG gives a public user key (user ID) for each data owner and gives a private key to each user in the system. We will provide two authentication techniques in this simulation; the CAPATCHA and the OTP. The CAPATCHA technique is used to provide the security of the system.
It is utilized to looks at a face pictures against a Template face pictures, whose identity being claimed. On the complement, face identification is a 1: N problem. It is used compares a query face image against all image templates in a face database. Face recognition has distinct advantages over biometrics systems using finger print/palm print and iris, because of its non-contact process. It is mainly used in security systems.
Cryptography is a technique or method to secure personal data from unauthorized user. In cryptography two types of operation are performed. (i) Encryption and (ii) Decryption. To encrypt and decrypt data a secret key is used. After encryption original data is converted into another format known as cyphertext, which is not easy to understand.
Steganography mainly aims to hide the data in a cover medium so that no one can suspect the existence of secret information which is hidden behind it. For this purpose, many different carrier file formats are used such as audio, video, text, and image. The most popular carrier for steganography is the image because of their frequency on the internet, so hiding the data behind image file is known as image steganography. Secret data hiding in digital images has drawn much attention in recent years. II.
ANANTH SAI KRISHNA BATTINENI BELLEVUE UNIVERSITY CIS612-T202 – COMPUTER PLATFORMS AND NETWORKING ASSIGNMENT 11.2 Passwords: Passwords provide authorization for a particular user. The correct characters will grant access to operate the system. Every operating system has the option to enable passwords for the computer system to help the user to avoid the unauthorized use of the system. Password Policy: The rules set to make the computer secure are called password policies. The policies provide a way to create a password which is hard for the hackers to steal it.
Secret code is applied to the message and hashed and is sent to the receiver 6. Secret code is applied to the message and hashed and this hashed message is encrypted and sent to the receiver. It is used in digital signatures the hash is encrypted using sender’s private key and then encrypted using public key and sent to the receiver and the receiver decrypts the message using the private key. It is used in password storage A good system does not store the plaintext equivalent but store something else which include some randomness .so now if we use hash and because of its onewayness it is impossible to get back the password. If we use pure hash in the password and encrypt it, it can be broken easily by exhaustive search so that is why we have add some randomness to the password before the hash function is applied.
Developers implement minimum privilege principles and perform error handling. Meticulous to minimize the risk of increased privileges. All as confidential information must use an integrity selection mechanism, such as HMAC-SHA1, or a digital signature to limit the risk of violation. Availability: Since owners of records are granted the right of access to their own records, a lack of availability of service may result in breach of HIPAA compliance. Developers propose systems to properly handle errors and resist denial of service attacks.
How we can protect the data in transit in a variety of applications such as data transfer on the Internet, and on cellular phone networks. a) Encryption b) Data mining c) Internet Security d) Decryption Answer:a 2. Which key is used to access the encrypted message? a) Encryption key b) Decryption key c) Primary key d) Foreign key Answer:b 3. Which of the following is a property of good encryption technique?
Explain the growth trend in this area With any network, you need to provide several resources for your users, but chief among them is security. Security starts with ensuring that only the right people have access to your network, and that they only have access to what they are supposed to have access to. Next comes the ability to ensure that communications are protected, and systems are inspected for vulnerabilities and threats. Identity as a Service (IDaaS) is a solution that provides authentication infrastructure as a cloud service. IDaaS is a service that provides Identity and Access Management (IAM) functions for a company in place of a local solution like Active Directory.
