Despite the capabilities of Android mobile phones, compared in specification to personal computers a few years ago, few programs for applied steganography has been written for such devices. Our objective is to produce an application that uses echo steganography to hide a short text message in an audio message recorded by the user, and then share that message. Someone with the same application o...

High transmission efficiency, low resource occupancy and intelligible meaning make text message as the most commonly used type of media in our daily communication. Text steganography, an information hiding technology based on text message, has been a new exploring research in recent years. Due to the restriction of redundant information as well as its alterability in manual operation, text mess...

Short message noisy network coding (SNNC) differs from long message noisy network coding (LNNC) in that one transmits many short messages in blocks rather than using one long message with repetitive encoding. Several properties of SNNC are developed. First, SNNC with backward decoding achieves the same rates as SNNC with offset encoding and sliding window decoding for memoryless networks where ...

This paper concerns a modified approach of compressing Short Bengali Text Message for small devices. The prime objective of this research technique is to establish a lowcomplexity compression scheme suitable for small devices having small memory and relatively lower processing speed. The basic aim is not to compress text of any size up to its maximum level without having any constraint on space...

Pervasive computing provides an attractive vision for the future of computing. Mobile computing devices such as mobile phones together with a land-based and wireless communication network infrastructure are the existing technical prerequisites for continuous access to networked services. The security of the system is a high concern in this environment, as well as its usability. This paper prese...

In the broadband era, narrowband short message service (SMS) is still the most popular wireless data service. Many studies have been conducted to investigate the performance of SMS based on the arrival rates of short messages. From Chunghwa Telecom’s commercial SMS call data records, we observed that even if the SMS arrival rates are the same, the distributions for the number of SMS arrivals pe...

The use of Automated Teller Machine (ATM) has become an important tool among commercial banks, customers of banks have come to depend on and trust the ATM conveniently meet their banking needs. Although the overwhelming advantages of ATM cannot be over-emphasized, its alarming fraud rate has become a bottleneck in it’s full adoption in Nigeria. This study examined the menace of ATM in the socie...

Khaled Baqer: What I’d like to do first is to highlight the background and motivation for the payment project that we’re working on at Cambridge. I’ll do a ten-minute introduction and Ross will take over to discuss some of the attacks and the interesting parts of this paper. The story begins with the mobile payment revolution. This is not Apple Pay, Google Pay or whatever extension of EMV you h...

We introduce a framework for a new idea tool Note, which gathers, fosters and manages innovative ideas. Note supports the development of organizational memory and is connected to the practices of organizational innovativeness. The tool utilizes text mining methods in idea processing, management and visualization and is thus a new approach in idea management software. The tool is under development.

With the rapid increase of the short message service in China, the information query technology based on the Chinese natural language is becoming a research hotspot at present. An algorithm of the Chinese natural language understanding based on certain domain knowledge is proposed, and it is applied to a Chinese short message based information query system. The algorithm is divided into three i...
