Data security is a way to ensure that stored data is safe from corruption and that access to it is accordingly controlled. Data security helps to ensure privacy. It also helps protect personal data from theft. Data theft is one that often occurs on global computer networks. It includes criminal acts in the internet world. Chronology of theft is that an intruder enters a system and retrieves essential information without the owner's knowledge. Intruders use data that has been taken for various crimes. Various ways that intruders take to retrieve the data. This action is proven by the amount of internet traffic that is looking for a gap to infiltrate a system. Cryptography is needed to protect essential data. One of the classic algorithms used is Gronsfeld Cipher. This algorithm works by exchanging characters in messages using substitution tables. The key used is a number that determines the shift of plaintext and key. The resulting ciphertext is the result of plaintext substitution with the key table. This algorithm is constructive for users to secure their essential information when it will be sent through a global network.

Along with the development of current technology, making technology is very important in today's life. Security level digital data has become more vulnerable to exploitation, the problem arises when an information technology device was attacked by people who do not want to take a responsible and important data illegally, so the administrator must act quickly to secure important data. Making a data security technology on the internet is very important information. Limitations administrator underlying the creation of a system that is able to detect and defense systems against such attacks is automation, so that it can be applied to data security. The system is built to prevent attacks on computer networks with more specific on THC - Hydra. This system will analyze the number of errors in the log into the database, and if the error exceeds the tolerance rules are made by the administrator. If the error is more than 3 times in one minute, then with automation, the system will create a rule that can imprison users who do not have such access, and access to the prison in the illegal user can not perform such activities on legal access and access to activities conducted illegal user can be recorded on a file and jail.txt. So under any circumstances and not in supervising administrator, the security of other user data will be safe and can not be retrieved or viewed by a user of illegal access.

The amount and range of information on the Internet is growing at a rapid pace. Cisco systems report (2008) expects Internet traffic growth to be spurred by video, social networking and collaboration applications collectively referred to as Web 2.0 technologies. The Cisco systems report (2008) forecasts that “global Internet Protocol (IP) traffic will increase by a factor of six from 2007 to 2012, reaching 44 exabytes per month in 2012, compared to fewer than 7 exabytes per month in 2007.” ComScore report (2009) estimates that the total global Internet audience has surpassed 1 billion visitors in December 2008. Magid Abraham, CEO of ComScore Inc., says “Surpassing one billion global users is a significant landmark in the history of the Internet. It is a monument to the increasingly unified global community in which we live and reminds us that the world truly is becoming more flat. The second billion will be online before we know it, and the third billion will arrive even faster than that, until we have a truly global network of interconnected people and ideas that transcend borders and cultural boundaries.” The increase in Internet traffic is aided because making information available online is becoming relatively inexpensive, and as more people have Internet access demand for information increases. The trend of increasing Internet traffic is likely to continue (Datta et al. 2003, Cisco systems report 2008).

<p align="center"><strong><em>Abstract</em></strong></p><p><em>There are several security aspects of the data that must be maintained, such as: authentication, integrity, non repudiation, authority, confidentialty, privacy and access control. One of the vulnerable parts of data security is when sending data to the destination. At the time of delivery, tapping of data can occur, so that people who are not entitled to get that information can find out. Therefore, an information needs to be secured so that only people who have access rights can know or get that information. And to maintain the confidentiality of the information, one of the ways is to insert the data into other objects, so that other people do not realize if the object contains important data or information. This hiding method is also known as steganography, and cryptography is added to strengthen the security of the data, that is a science and art to maintain the confidentiality of the message by encoding it in a form that is incomprehensible. The method used in steganography is Least Significant Bit (LSB), the algorithm used in cryptography is the Advanced Encryption Standard (AES), and the software development method used is prototype. The results of this study are all aspects of data security can be achieved, including when passing through the process of sending data through media such as the internet.</em></p><p><strong><em>Keyword: </em></strong><em>Steganography, Criptography, Prototype.</em></p><p align="center"><strong><em>Abstrak</em></strong></p><p><em>Ada beberapa aspek keamanan data yang harus dijaga, seperti: otentikasi, integritas, non repudiation, otoritas, kerahasiaan, privasi, dan kontrol akses.

The rise of the Internet of Things (IoT) has driven mobile applications development. As a result, in the consumer IoT (CIoT) space, any product usually comes with a smartphone application to either control, programme, or just view what is happening with the product. The IoT brings with it opportunities and challenges to consumers. For example, IoT technology makes it possible to connect all of a person’s devices to create a smart eco-system or assemblage. However, the biggest threat in CIoT is personal data security. This study utilized a qualitative narrative inquiry and Delphi technique to explore data security issues that come with CIoT assemblages and associated mobile applications in South Africa. The study established that consumers enjoy the convenience and benefits that IoT technology brings. It is concluded that for CIoT to thrive, safety is crucial, and all the stakeholders in the IoT assemblage need to ensure the protection of consumers.

Symmetric Key

Security of data stored on computers is now an absolute requirement, because every data has a high enough value for the user, reader and owner of the data itself. To prevent misuse of the data by other parties, data security is needed. Data security is the protection of data in a system against unauthorized authorization, modification, or destruction. The science that explains the ways of securing data is known as cryptography, while the steps in cryptography are called critical algorithms. At this time, there are many cryptographic algorithms whose keys are weak especially the symmetric key algorithm because they only have one key, the key for encryption is the same as the decryption key so it needs to be modified so that the cryptanalysts are confused in accessing important data. The cryptographic method of Word Auto Key Encryption (WAKE) is one method that has been used to secure data where in this case the writer wants to maximize the encryption key and description of the WAKE algorithm that has been processed through key formation. One way is to apply the algebraic pascal triangle method to maximize the encryption key and description of the WAKE algorithm, utilizing the numbers contained in the columns and rows of the pascal triangle to make shifts on the encryption key and the description of the WAKE algorithm.Keywords: Cryptography, WAKE, pascal

Public Disclosures

Digitization and the release of public records on the Internet have expanded the reach and uses of criminal record data in the United States. This study analyzes the types and volume of personally identifiable data released on the Internet via two hundred public governmental websites for law enforcement, criminal courts, corrections, and criminal record repositories in each state. We find that public disclosures often include information valuable to the personal data economy, including the full name, birthdate, home address, and physical characteristics of arrestees, detainees, and defendants. Using administrative data, we also estimate the volume of data disclosed online. Our findings highlight the mass dissemination of pre-conviction data: every year, over ten million arrests, 4.5 million mug shots, and 14.7 million criminal court proceedings are digitally released at no cost. Post-conviction, approximately 6.5 million current and former prisoners and 12.5 million people with a felony conviction have a record on the Internet. While justified through public records laws, such broad disclosures reveal an imbalance between the “transparency” of data releases that facilitate monitoring of state action and those that facilitate monitoring individual people. The results show how the criminal legal system increasingly distributes Internet privacy violations and community surveillance as part of contemporary punishment.
