Abstract: It is important to differentiate between various objects and places in the real world. Any Smartphone equipped with a camera can read the content of QR code directly. QR codes being a two dimensional codes are useful in storing the information.This information isn’t present in human readable form hence an individual cannot anticipate whether this is a valid information or a maliciously manipulated code. QR Codes can be used for attacking both the human interaction and the automated systems. While the humans may fall for various phishing attacks, the automated systems are vulnerable to command injections and SQL injection. This paper examines the QR codes different attacks. Though it is easy to modify the information stored in the QR code but one must make sure that the identifier written in the QR code is issued by an authorized organization.

on extensions of type systems, and history-based access control. In general, security checks are crosscutting concerns and are hard to modularize. The paper describes how most of existing methods can be implemented in a more modular and evolutionfriendly fashion with the help of aspect-oriented techniques

As sensor networks edge closer towards wide-spread deployment, security issues become a central concern. So far, the main research focus has been on making sensor networks feasible and useful, and less emphasis was placed on security. We design a suite of security building blocks that are optimized

This paper gives the main definitions relating to dependability, a generic concept including as special case such attributes as reliability, availability, safety, integrity, maintainability, etc. Security brings in concerns for confidentiality, in addition to availability and integrity. Basic

significant security concerns. Therefore, it is desirable to create a secure environment to contain untrusted helper applications. We propose to reduce therisk of a security breachby restricting the program's access to the operating system. In particular, we intercept and filter dangerous system calls

Abstract. In this paper we show how design-level aspects can be used to separate security concerns from essential functional concerns during software design. The aspect-oriented design technique described in this paper allows one to independently specify security and essential functional concerns

This paper attempts to list all instances of certain types of security problems in the X Protocol. Issues with authorization are not addressed. We assume that a malicious client has already succeeded in connecting, and try to assess what harm it can then do. We propose modifications

outline a number of areas of concern. In some cases, there are features that would have a negative impact on security if nothing else is done. It may be desirable to adopt the features anyway, but in that case, the
