| Summary: | There are many ways to prevent the sensitive information from unauthorized manipulation. Time stamping is one of the ways to prevent the information by keep tracking time creation of the document. Based on the existing research, there are several techniques that implemented time stamping method for a document. In this study, implementing time stamping method for medical record system is the main objective. The integrity of patient medical data is important and therefore the medical record need a mechanism that can verify the record from unauthorized manipulation. The components that included in this proposed time stamping method are MAC (Media Access Control) Address and hash function (SHA512). Besides that, this proposed method also provides a link between a record to another record. That link is produced by including hash value of previous record to the time stamp. This proposed method introduced several functionalities for the medical record. The first functionality is to trace creation time of each record, by recording of the time when the document was time-stamped. The second functionality is to trace who is the creator of the record. The third functionality is to trace which computing device that has been used to create the record by examining the MAC Address. And the last functionality is to prevent the possibility of unauthorized document was put between the documents that already stored in the database by implementing linking hash value. Thus by implement this proposed method, the sensitive information of medical record can be prevented from updated and manipulation by unauthorized people. |
