SIMULATION MODEL OF VISIBLE WATERMARKING FOR JPEG IMAGE (3 D) USING VLSI/MATLAB
Watermarking is the process that embeds data called a watermark, a tag, or a label into a multimedia object, such as images, video, or text, for their copyright protection. According to human perception, the digital watermarks can either be visible or invisible. A visible watermark is a secondary translucent image overlaid into the primary image and appears visible to a viewer on a careful inspection. The invisible watermark is embedded in such a way that the modifications made to the pixel value is perceptually not noticed, and it can be recovered only with an appropriate decoding mechanism. This project presents a new very large scale integration (VLSI) architecture for implementing two visible digital image watermarking schemes. The proposed architecture is designed to aim at easy integration into any existing digital camera c

The Industrial Technology Research Institute (ITRI) will sponsor the 16th International Symposium on VLSI Technology, Systems and Applications (2009 VLSI-TSA) from 27 to 29 April 2009 at the Ambassador Hotel in Hsinchu, Taiwan. The symposium program will cover 2.5 days technical sessions including 3 plenary talks, two special sessions focusing on Green Devices and Next Generation Lithography, and numbers of contribution sessions followed by a half-day short course. The Best Student Paper Award for the 2008 Symposium will be presented at the opening of the symposium and the Best Student Paper Award for the 2009 Symposium will again be selected during the conference. The conference is proud to create an annual platform for technical exchanges by experts from all over the world on the advancements in semiconductor research, development, and manufacturing. The 2009 VLSI-TSA will hold a joint-opening with the International Symposium on VLSI Design, Automation and Test (2009 VLSI-DAT), joint keynotes from both design and technology field will give penetrating speeches to all the audience. The highlight of three keynote speeches shows below: Dr. Mark Pinto, Applied Materials, USA Topic: Has The Sun Finally Risen on Photovoltaics? Dr. Rene Penning de Vries, NXP, The Netherlands (Joint Keynote) Topic: From Living Faster to Living Better Dr. Ken Uchida, Tokyo Institute of Technology, Japan Topic: Carrier Transport and Stress Engineering in Advanced Nanoscale MOS Transistors With its Hsinchu Science-based Industrial Park, in 2007 Taiwan generating over 68.0% of the global semiconductor foundry revenue, 25.1% of the world DRAM production revenue, 23.7% of fabless revenue, and 53.0% of independent IC packaging revenue, Taiwan is doubtlessly one of the major dynamos of the semiconductor industry on this planet. Join us at the VLSI-TSA technical programs as well as the culture tour to experience historic Hsinchu city, in which the technical and cultural atmosphere have been harmoniously connected. The 2008 VLSI-TSA has successfully attracted about 500 attendees with a very high-quality program featuring three keynote speeches, two special sessions, 22 invited talks, nine technical sessions with 54 technical papers presented, and two short courses. Both the contributing and invited papers are of high quality, and are presented by industrial and academic leaders and students from over 10 countries.. Starting 2006, the VLSI-TSA split its design segment to become the International Symposium on VLSI Design, Automation and Test (VLSI-DAT).

Subscriber Identity Module (SIM)

Subscriber Identity Module (SIM)

Main article: Subscriber Identity Module

One of the key features of GSM is the Subscriber Identity Module, commonly known as a SIM card. The SIM is a detachable smart card containing the user's subscription information and phone book. This allows the user to retain his or her information after switching handsets. Alternatively, the user can also change operators while retaining the handset simply by changing the SIM. Some operators will block this by allowing the phone to use only a single SIM, or only a SIM issued by them; this practice is known as SIM locking, and is illegal in some countries.

In Australia, North America and Europe many operators lock the mobiles they sell. This is done because the price of the mobile phone is typically subsidised with revenue from subscriptions, and operators want to try to avoid subsidising competitor's mobiles. A subscriber can usually contact the provider to remove the lock for a fee, utilize private services to remove the lock, or make use of ample software and websites available on the Internet to unlock the handset themselves. While most web sites offer the unlocking for a fee, some do it for free. The locking applies to the handset, identified by its International Mobile Equipment Identity (IMEI) number, not to the account (which is identified by the SIM card).

In some countries such as Bangladesh, Belgium, Costa Rica, India, Indonesia, Malaysia, and Pakistan, all phones are sold unlocked. However, in Belgium, it is unlawful for operators there to offer any form of subsidy on the phone's price. This was also the case in Finland until April 1, 2006, when selling subsidized combinations of handsets and accounts became legal, though operators have to unlock phones free of charge after a certain period (at most 24 months).

[edit] GSM security

GSM was designed with a moderate level of security. The system was designed to authenticate the subscriber using a pre-shared key and challenge-response. Communications between the subscriber and the base station can be encrypted. The development of UMTS introduces an optional USIM, that uses a longer authentication key to give greater security, as well as mutually authenticating the network and the user - whereas GSM only authenticates the user to the network (and not vice versa). The security model therefore offers confidentiality and authentication, but limited authorization capabilities, and no non-repudiation. GSM uses several cryptographic algorithms for security. The A5/1 and A5/2 stream ciphers are used for ensuring over-the-air voice privacy. A5/1 was developed first and is a stronger algorithm used within Europe and the United States; A5/2 is weaker and used in other countries. Serious weaknesses have been found in both algorithms: it is possible to break A5/2 in real-time with a ciphertext-only attack, and in February 2008, Pico Computing, Inc revealed its ability and plans to commercialize FPGAs that allow A5/1 to be broken with a rainbow table attack.^[13] The system supports multiple algorithms so operators may replace that cipher with a stronger one.

Network structure

Network structure

The structure of a GSM network

The network behind the GSM seen by the customer is large and complicated in order to provide all of the services which are required. It is divided into a number of sections and these are each covered in separate articles.

• the Base Station Subsystem (the base stations and their controllers).
• the Network and Switching Subsystem (the part of the network most similar to a fixed network). This is sometimes also just called the core network.
• the GPRS Core Network (the optional part which allows packet based Internet connections).
• all of the elements in the system combine to produce many GSM services such as voice calls and SMS.
