SMS: Impacto social y cognitivo
Alonso,Elena; Perea,Manuel;
Escritos de Psicología (Internet) , 2008,
Abstract: the growing use of mobile text messages (hereinafter sms) has given place to a debate on the social impact and the psychological effects of this new mass media. in the recent years the massive use of mobiles and internet has generated a new way of communication based on the abbreviated use of language. in this work we examine the role of sms as an effective tool of communication in the way of establishing social relationships among young individuals. furthermore we examine the reading cognitive cost of sms; and derived from this analysis and the content of the sms sentences we extract two conclusions. the first one is that sms language is economical enough to transfer relevant information using the abbreviated language even though it implies a reading cost, the second conclusion is that sms language implies a socio-cultural aspect worthy to be reflected on.

The SMS Chaum Mix  [PDF]
Matthew Rothmeyer, Dale R. Thompson, Matthew Moccaro
Journal of Computer and Communications (JCC) , 2014, DOI: 10.4236/jcc.2014.24010
Abstract:

Mobile devices such as smartphones are prime candidates for the application of mixing techniques to provide anonymity for small groups of individuals numbering 30 to 40 members. In this work, a Chaum mix inspired, smartphone based network that uses the Short Message Service (SMS) is proposed. This system leverages both techniques used by current anonymity networks as well as knowledge gained from current and past research to make messages private and untraceable. Previously published attacks to anonymous systems are addressed as well as mitigation techniques.

Image Transference and Retrieval over SMS
Muhammad Fahad Khan,Saira Beg,Fakhra Kashif
International Journal of Computer Science Issues , 2011,
Abstract: Paper describes the method of sending colorful images and animations through SMS (Short Message Service) over GSM (Global System for Mobile Communications) network. Presented method has two main blocks; first block converts images or animations into characters. And second block applies Huffman coding compression method on those characters and set them as a payload text of SMS. Generally, SMS is text based service and cannot send multimedia contents. For delivering multimedia contents, two other services are utilized which are; MMS (Multimedia Messaging Service) and EMS (Extended Messaging Service). EMS is an application level extension; can transfer predefined sounds, animations and images etc. But a drawback is that EMS is not supported as widely as SMS. On the other hand, MMS have richer contents than SMS and EMS. But for large files it needs higher network capability like 3G etc. Enabling colored images (raster/vector) and animation features in SMS we develop an application using J2ME platform.
Reformulation and Interpretation of SMS Braneworld  [PDF]
Edward Anderson,Reza Tavakol
Physics , 2003, DOI: 10.1088/0264-9381/20/23/L01
Abstract: We reformulate the Shiromizu, Maeda and Sasaki (SMS) braneworlds within the framework of the five-dimensional Einstein equations. In many applications of the braneworld Einstein field equations, the Weyl term is attributed to the bulk, thus splitting the non-Einsteinian terms into `bulk' and `brane' terms. Here by employing standard geometrical identities, we show that such a split is non-unique, since these terms get mixed up in different formulations. An important consequence of this non-uniqueness is that even though the full brane-bulk systems in all such formulations are completely equivalent, important differences can arise were one to truncate different formulations by throwing away the associated `bulk' terms. This is particularly likely to be the case in more general anisotropic/inhomogeneous settings with non-AdS bulks, in which the usual truncation of the SMS (which throws away the Weyl term) would not coincide with the full system. We emphasize that rather than providing support for any truncation, these differences show clearly the dangers of using any truncated equations and provide a strong argument in favour of studying the full brane-bulk system. The different formulations we provide also permit different ways of approaching the full brane-bulk system which may greatly facilitate its study. An example of this is the second-order nature of the formulations given here as opposed to the SMS's formulation which is third-order.
Selling train tickets by SMS  [PDF]
Steven Meyer
Computer Science , 2011,
Abstract: Selling train tickets has evolved in the last ten years from queuing in the railway station, to buying tickets on the internet and printing them. Both alternatives are still viable options, though they are time consuming or need printing devices. Nowadays it is essential to offer a service that is as fast and efficient as possible: mobile phones provide an accessible, affordable and widely available tool for supplying information and transferring data. The goal of this project is to design a train ticket contained in a SMS message. While there are several challenges related to the project, the main one is the security and how we can digitally sign a train ticket that is contained in 160 characters. The solution offered in this project is the implementation of the MOVA Signature (from the name of the inventors MOnnerat and VAudenay) that uses an interactive verification and therefore allows signature of 20 bits (roughly 4 characters).
Hybrid Compression Encryption Technique for Securing SMS
Ahmed M Mahfouz,Awny A. Ahmed,Bahgat A. Abdel-latef,Tarek
International Journal of Computer Science and Security , 2010,
Abstract: Mobile communication devices have become popular tools for gathering and disseminating information and data. When sensitive information is exchanged using SMS, it is crucial to protect the content from eavesdroppers as well as ensuring that the message is sent by a legitimate sender. Using an encryption technique to secure SMS data increases its length and accordingly the cost of sending it. This paper provides a hybrid compression encryption technique to secure the SMS data. The proposed technique compresses the SMS to reduce its length, then encrypts it using RSA algorithm. A signature is added to the encrypted SMS for signing it to differentiate it from other SMS messages in SMSINBOX. The experimental results which are based on Symbian OS show that the proposed technique guarantees SMS data security without increasing its size.
Hand Anthropometry and SMS Satisfaction  [PDF]
Vimala Balakrishnan,Paul H. P. Yeow
Journal of Applied Sciences , 2008,
Abstract: The effect of hand anthropometry on Short Message Service (SMS) satisfaction was investigated using structured questionnaire interviews with 110 subjects, aged between 17-25 years old. Hand size was measured to assess its effect on mobile phone design factors satisfaction whereas thumb circumference and length were measured for keypad design factors. Small hand-sized subjects were found to be more satisfied with mobile phone dimensions than large hand-sized subjects. Thumb circumference significantly affects users` satisfaction towards key size and space between keys whereas thumb length significantly affects keypad layout satisfaction. Both thumb circumference and length significantly correlate negatively with the corresponding keypad design factors. Results confirm that hand anthropometry do affect users messaging satisfaction. These findings should prove useful to mobile phone designers who could look into the possibility of designing customized mobile phones that cater to large hand and thumb sized users, so as to increase their subjective satisfaction.
Analysis of Mobile Users’ Perception towards SMS Voting  [cached]

Communications of the IBIMA , 2008,
Abstract: Voting through Short Message Service (SMS) technology is fast and reliable as the mobile technology in Malaysia is quite advanced. Most of the SMS voting mechanism is easily understood by the public. There is no need to explain the voting process in detail as almost 80% of the mobile users know how to use the SMS service. SMS voting is just another way of sending a vote to the recipient by using short code instead of using a normal mobile number. SMS voting provides a useful, secure and reliable process as mobile users are informed of the charges incurred and receive a return SMS to acknowledge that their SMS vote has been received. The objective of this study is to study the characteristics of SMS voting adopters in terms of demographic factors as well as to explore the mobile users’ perception towards SMS voting. A survey using questionnaires was conducted to gain information and opinions from a convenience sample of 300 Malaysian mobile users regarding their perceptions on using SMS to vote. The findings revealed that approximately two-thirds of the Malay respondents use SMS voting, most mobile users in the sample are single and female, and that mobile users like to send their votes using SMS. There is a significant difference between the usage of SMS voting among female respondents. Of the respondents 80 per cent perceive that the ease of use factor has greatly influenced mobile users in using SMS for voting purposes.
