Steganography is the science of invisible communication. Apart from the sender and intended recipient no one suspects the existence of the message. Using Steganography, information can be hidden in various mediums known as carriers. The carriers can be images, audio files, video files and text files. Image Steganography is a technique of using an image file as a carrier. Cryptography protects the information by applying the encryption and decryption techniques, so that the secret message can be understood only by the right person.This paper proposes a method, which combines the techniques of Steganography and cryptography, to hide the secret data in an image. In the first phase, the sender will embed the secret data in an image by using the Least Significant Bit (LSB) technique. The embedded image will be encrypted by using an encryption algorithm. At final, the encrypted image will be decrypted and the hidden data will be retrieved by supplying the valid secret key by the receiver. The process includes the phases of Data embedding, Image Encryption and recovery of both original image and secret data from the encrypted image.

Abstract Evaluators must understand the complex overall process that makes up an independent medical evaluation (IME), whether the purpose of the evaluation is to assess impairment or other care issues. Part 1 of this article provides an overview of the process, and Part 2 [in this issue] reviews the pre-evaluation process in detail. The IME process comprises three phases: pre-evaluation, evaluation, and postevaluation. Pre-evaluation begins when a client requests an IME and provides the physician with medical records and other information. The following steps occur at the time of an evaluation: 1) patient is greeted; arrival time is noted; 2) identity of the examinee is verified; 3) the evaluation process is explained and written informed consent is obtained; 4) questions or inventories are completed; 5) physician reviews radiographs or diagnostic studies; 6) physician records start time and interviews examinee; 7) physician may dictate the history in the presence of the examinee; 8) physician examines examinee with staff member in attendance, documenting negative, physical, and nonphysiologic findings; 9) physician concludes evaluation, records end time, and provides a satisfaction survey to examinee; 10) examinee returns satisfaction survey before departure. Postevaluation work includes preparing the IME report, which is best done immediately after the evaluation. To perfect the IME process, examiners can assess their current approach to IMEs, identify strengths and weaknesses, and consider what can be done to improve efficiency and quality.

Abstract. Background: Congenital venous malformations are frequently treated with sclerotherapy. Primary treatment goal is to control the often size-related symptoms. Functional impairment and aesthetical aspects as well as satisfaction have rarely been evaluated. Patients and methods: Medical records of patients who underwent sclerotherapy of spongiform venous malformations were reviewed and included in this retrospective study. The outcome of sclerotherapy as self-reported by patients was assessed in a 21 item questionnaire. Results: Questionnaires were sent to 166 patients with a total of 327 procedures. Seventy-seven patients (48 %) with a total of 159 procedures (50 %) responded to the survey. Fifty-seven percent of patients were male. The age ranged from 1 to 38.1 years with a median age of 16.4 years. The lower extremities were the most common treated area. Limitations caused by the venous malformation improved in the majority of patients (e.g. pain improvement 87 %, improvement of swelling 83 %) but also worsening of symptoms occurred in a minority of cases. Seventy-seven per cent would undergo sclerotherapy again. Conclusions: Sclerotherapy for treatment of venous malformations results in significant reduction of symptoms. Multiple treatments are often needed, but patients are willing to undergo them.
