Data is the essential thing in the world of communication. Text messaging is a way of communicating that is sent in digital form. This message is very widely used in electronic media such as short message service. This message was sent through the service provider. Messages sent are unsafe and can be intercepted at the time of submission. Message delivery needs to apply cryptographic algorithms to text messages sent using encryption and decryption techniques. Super Playfair cipher and two square cipher algorithms are a development of Playfair cipher method. This method is a quite complicated way of solving it than other classical methods. These methods belong to classical cryptographic algorithms that use substitution encoding techniques and character transitions that use a symmetric key in the process of encryption and decryption.

Cryptographic Techniques

SMS (Short Message Service) is a popular communication technology revolution. The development of computerized technology has been very advanced. SMS is very vulnerable to data theft or theft by irresponsible parties. For the sake of maintaining the security of SMS can be done by using cryptographic techniques. Cryptographic techniques can encode text messages by encrypting them into passwords that are not understood. Mars algorithm is an algorithm that uses a 128-bit key and the encryption process consists of 32 rounds. This symmetry algorithm will produce a higher level of security for the ultrasound image because it can encode it into a form of cipher with a process that is complex enough so that it will be difficult for cryptanalysts to access the image. This research will use the Mars algorithm for the encryption and decryption process, so the process needs to go through several long stages in order to produce the final cipher. This study describes the process of securing SMS by encoding it based on the Mars algorithm, in the form of a password that is difficult for others to understand and understand. This is done as an effort to minimize acts of misuse of SMS

The aim of this study is to investigate the choice of alphabetical encoding in Greek text-messaging (or Short Message Service, SMS). The analysis will be based on a corpus of 447 text-messages exchanged among participants who belong to the age group of ‘youth’ (15-25 years old) and live in Athens (Greece). The data analysis will show that the standard practice of writing with Greek characters represents the norm in Greek SMS. The script norm will be discussed in relation to the medium’s technological affordances and the participants’ stance towards new media. The analysis will then focus on non-standard graphemic choices, such as the use of both, Greek and Roman, alphabets in the encoding of single messages. It will be demonstrated that such marked choices are employed as a means of indexing the participants’ affiliation with global popular cultures and enhancing expressivity in a medium of reduced paralinguistic cues.

Studies have shown COVID-19 patients may have a low oxygen saturation (SpO2) independent of visible respiratory distress, a phenomenon termed “silent hypoxia.” Silent hypoxia creates uncertainty in the outpatient setting for clinicians and patients alike. In this study, we examined the potential for pulse oximeters in identifying early signs of clinical deterioration. We report descriptive results on COVID-positive patients’ experiences with a comprehensive home monitoring tool comprised of home SpO2 measurements with a novel symptom-tracking short message service/text messaging application. Of patients who required hospitalization, 83% sought care as a result of low pulse oximeter readings. Nearly all patients who did not require hospitalization reported that having a pulse oximeter provided them with the confidence to stay at home. Essentially all patients found a home pulse oximeter useful. Keeping COVID-19-positive patients at home reduces the potential for disease spread and prevents unnecessary costs and strain on the healthcare system.

Message Service

The increasing number of short message service which has grown rapidly has bad impact towards its service quality. Delay in the system could increase while message delivered because the network gets burdened. Aplication Comresion text metode (  iD-Code companding algorithm)  for predictive text has mode to reduce bits representation for each character. In the other hand by choosing new route like General Packet Radio Service (GPRS) will also significantly help to reduced burden of the network and also may achieve high rate of message delivery process. Based on analysis obtained that iD-Code Algorithm could truncates bit representation of predictive text file until 50% of value, with character average length only 4 bits. The implementation of iD-Code Algorithm also lead to the decreasing of packet holding time that also have impact reducing the packet delay time queue and further it will lead to the channel using efficiency.

Randomize Response

Short message service (SMS or text messaging) surveys can collect data quickly and inexpensively. However, SMS surveys have space constraints that pose difficulties to questionnaire designers: Questions can only be 160 characters or less, surveys must be short, and many respondents use phones with small screens. In this article, we compare SMS and benchmark face-to-face surveys across four African countries to address three common questions in SMS questionnaire design. First, are multiple response questions feasible? Second, is it necessary to randomize response option order? Third, should “don’t know” response options be included? Our results provide practical guidance about how to improve data quality with this emerging mode of data collection.

The equipments in computer rooms are complicated in nature. Many factors may influence their normal operations, for example: voltage, temperature, humidity, and the normalcy of systems. It would be prudent to have a monitoring system to prevent from unpredictable problems. Most monitoring systems in the market can only issue alarms in abnormal situations and then analyze the aftermath. They are also expansive and lack the ability for distant instant control. To tackle this problem, after our successful and practical experiments, we utilize GSM text messaging ability (i.e. SMS, short message service) and make distant monitoring possible. The monitoring system is established with a reasonable price that is well below current market. With this system, the manager/administrator can monitor the real-time status of equipments in computer rooms, send control commands through SMS and then get them executed to solve the problems instantly and effectively.

This paper presents an SMS based design in the GSM system for a portable, light weighted, and small sized TeleAlarm device. The device is composed of a transmitter and a controller. When an emergent situation such as a stroke or a fall occurs, the user only needs to push a button to trigger the controller. The controller automatically sends text messages stored in its database through the transmitter to specified mobile phone numbers for help. The SMS uses only the control channels in the GSM system to transfer the message, which enables the receiving-end user to receive it even during a call. An experimental test shows that a complete message transmission only needs 2.949 seconds in average. The design is convenient to elderly people who may live alone.
