#graphical password

In today's Mall shopping system, the users usually visit the mall for shopping di erent products and spend their valuable time in searching the products and the products in their price range. After selecting the product the users have to wait in a long queue for billing which is another time consuming part of shopping, and moving the cart from one place to another place is another hectic task. In this system the user's time and searching for products in the entire mall increases. So, we are working on this system to avoid these drawbacks. The drawbacks in the existing system are, rstly the time required for bill payment is more as the users have to wait in a long queue. Secondly, the users have to move the cart through the entire mall and carry a load of products at their home. One more drawback is regarding the barcode in which less data is stored. In view of the mobile phone has become popular consumer products, a simple optimization method was given to design shopping guide systems run on smartphones, with the help of QR code generation and recognition technology, wherein, we can store more data using the QR code. The proposed programs can show accurate and real time shopping destination, thus help shopping mall to mine customer data more accurately and scienti cally. In our system we are going to use QR code for every product using QR code generator, a user goes for shopping and wants to purchase a product, he will scan the QR code of the product using QR code scanner, from his Android device and he will get list of all the similar products in that range and any o ers and discounts related to that product, this is done using searching and sorting algorithms. Once the user scans and adds the product to the cart the data gets fed to the server and the bill gets generated after adding all the products to the cart. The bill is sent to the user on his device and the products are delivered home and also bill payment is done online. Nowadays it is di cult to deal with the text based password. As text can be easily detected, or if it is known then its risky to deal with such things when we have con dential systems with us. We can overcome this problem with the help of a graphical password with cued click points. This graphical password will be really helpful to secure the con dential systems. Cued click points are the concept in which Persuasive Cued Click points graphical password scheme which includes usability as well as security evaluations. There are a lot of e ects that are most well known about passwords such as that user cannot memorize complicated passwords which are simple to identify. 

In order to prevent intruders from looking into sensitive data in smartphones users will have their own security measures, but those security measures are traditionally available measures one among them is finger based pattern doodling which became quite popular among users, also studies show that it is easy to remember and use than alphanumeric text based passwords. But these patterns are static in nature which can be stolen using shoulder-surfing attack. Shoulder-surfing refers to attack which is made based on observation of attacker either directly, or indirectly using applications to record such as camera or key logger. In this paper we have introduced a concept of dynamic patterns which when user records his input for the first time the positions will remain same but the next time the positions of each pattern is changed dynamically, also there is one more concept called image falsification is used. Image Falsification means deceiving the attacker to the false image pattern instead of exposing the true image pattern and the true pattern remains known only to the user.
