The text is still plaintext, making it easier for the attacker to make use of it. Text data can be secured by several techniques. One of them is cryptographic techniques. Cryptographic techniques can secure secret text data by randomizing the hex value of the data into a data that cannot be recognized and read. One of the reliable algorithms is the eXtended Tiny Encryption Algorithm (XTEA) symmetry algorithm. The XTEA algorithm is a simple algorithm that is lightweight and fast in the encryption and decryption process. However, the concept of the symmetry algorithm is the encryption and decryption process using the same key. The security of this concept is very vulnerable if the key is leaked and is public. So that this can be optimized by generating keys using the Linear Congruential Generator (LCG) method. Key generation is used with prime numbers. The key sent to an eligible recipient is only the initial prime number. So that the recipient has to do key assembly first to carry out the decryption process. This can optimize the encrypted ciphertext using the XTEA algorithm.","PeriodicalId":115863,"journal":{"name":"Resolusi : Rekayasa Teknik Informatika dan Informasi","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126794621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Watermarking is a technique that can be used to determine the validity of digital data copyright. PDF digital document data that is not inserted with a watermark, the information is very vulnerable to change and can cause problems such as the authenticity of the information in it being doubted because everyone can be free to manipulate the information and then redistribute it. The one-to-one mapping method is used for the watermarking process by inserting images into a pdf file. The process is done by taking the intensity value in the pdf file and the watermark image for mapping the pixel values. The result is a watermarked pdf file. The results of the watermaking process of this pdf file can be used to determine the validity of the copyright so that the authenticity of the information in it is safely maintained. Thus, the owner of the digital data feels that he will send his data to other parties.","PeriodicalId":115863,"journal":{"name":"Resolusi : Rekayasa Teknik Informatika dan Informasi","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115224888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Determining the Algorithm Text mining is a process of mining data in the form of text where the data source is usually obtained from documents and the goal is to find words that can represent the contents of the document so that an analysis of the connectivity between documents can be carried out. Processes in text mining include tokenization, stemming and filtering processes. The method of collecting data is the library method. The stages of application development include process design, table design, implementation and system testing. The work in this final project uses a case study on a marketplace.
