A Trajectory Privacy Protect Method Based on Location Pair Reorganization

With the rapid development of mobile Internet and communication technology, location-based services (LBS) are widely used in our daily life. The server stores a large amount of user location data, and these location data constitute user trajectories. If trajectory information on the server is leaked, it will seriously endanger users’ privacy. Trajectory <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1"> <mi>k</mi> </math> -anonymity technology is one of the most important methods to protect the privacy of user trajectory. However, current trajectory <math xmlns="http://www.w3.org/1998/Math/MathML" id="M2"> <mi>k</mi> </math> -anonymity methods have less discussion on the semantic of stop point when selecting dummy trajectory, which leads to the fact that attacker can still exclude the dummy trajectory from the <math xmlns="http://www.w3.org/1998/Math/MathML" id="M3"> <mi>k</mi> </math> -anonymity set and infer the real trajectory by combining background knowledge with the semantic information of stop points. To address this problem, this paper decomposes the real trajectory into location pairs set; the set consists of start-end points and stop points. According to the similarity of location pairs, the similar location pairs in history trajectory set are used to generate dummy trajectory: firstly, extracting the start-end points and stop points from real trajectory and assigning semantic to them. Then, based on the semantic, temporal, and geographical attributes, eligible location pairs are selected from history trajectory set to construct equivalence class. Finally, according to the location pairs in equivalence class, <math xmlns="http://www.w3.org/1998/Math/MathML" id="M4"> <mi>k</mi> <mo>−</mo> <mn>1</mn> </math> dummy trajectories are generated to form a <math xmlns="http://www.w3.org/1998/Math/MathML" id="M5"> <mi>k</mi> </math> -anonymity set. We evaluate our method thoroughly with real dataset. The results show that our method achieve an effective data availability and higher privacy protection than other methods.
High speed low power multipliers based on reversible logic methods

The aim of this research is on multipliers with higher speed, less power consumption, and a lower-complexity lower range. Reversible logic has recently found extensive application in multiple areas including multipliers, low-power CMOS circuits, optical data processing, and quantum circuits. Here, reversible logic is used to create efficient multipliers that are constructed with Vedic mathematics, Baugh-Wooley, and Wallace tree architectures. A particularly nice thing about these proposed multipliers is that they all utilize known logical principles, such as the reversible Half Adder, the reversible Full Adder, the Dual Key Gate, and the Kogge Stone Adder. As a means of guaranteeing better performance, multiple multipliers are distinguished according to reversible logic circuits. Simulated and synthesized using the Xilinx ISE method, the results of the proposed design are investigated.
Teachers' opinion on the use of information and communication technology in teaching the environment and society

The use of information and communication technology largely provides an opportunity to develop students' digital competencies, facilitates the process of understanding the material and makes teaching more interesting and modern. Whether and to what extent the information and communication devices will be used within the scope of the subject the Environment and Society largely depends on how well-equipped schools are, but also on the opinion that the teacher has towards them. In that respect, the respondents of our research were teachers in the territory of the city of Belgrade who, through the Google questionnaire, filled in a five-point Likert-type scale. The results of the research indicate that there is no statistically significant difference in opinion on the introduction of digital technologies in the field of the Environment and Society between male and female teachers and also teacher who attended and did not attend a course on digital technologies during their studies. Teachers essentially have a positive opinion on the use of digital technologies within the scope of the subject the Environment and Society and schools should strive to be equipped with ICT so that teaching content from all areas is presented as clearly, interestingly and accurately as possible. The following research can deal with the opinion of younger school-age students on the use of ICT within the scope of the subject the Environment and Society, but also other areas
Exploring Over-smoothing in Graph Attention Networks from the Markov Chain Perspective

The over-smoothing problem causing the depth limitation is an obstacle of developing deep graph neural network (GNN). Compared with Graph Convolutional Networks (GCN), over-smoothing in Graph Attention Network (GAT) has not drawed enough attention. In this work, we analyze the over-smoothing problem in GAT from the Markov chain perspective. First we establish a connection between GAT and a time-inhomogeneous random walk on the graph. Then we show that the GAT is not always over-smoothing using conclusions in the time-inhomogeneous Markov chain. Finally, we derive a sufficient condition for GAT to avoid over-smoothing in the Markovian sense based on our findings about the existence of the limiting distribution of the time-inhomogeneous Markov chain. We design experiments to verify our theoretical findings. Results show that our proposed sufficient condition can effectively improve over-smoothing problem in GAT and enhance the performance of the model.
Android-Based Text Message Encryption and Decryption Application Using the Advanced Encryption Standard Algorithm

Kaur 2 Public High School is one of the State Senior High Schools in Kaur District, Bengkulu Province. Communication between teachers or teachers and students or students and students has so far been carried out through text message applications that are already available on users' smartphones so that they exchange information. However, the information sent has not been fully implemented by security, where the message sent is the original message, and the recipient of the original message can read it immediately. This of course makes it easier for certain parties who intend to get the message. An android-based text message encryption and decryption application using the Advanced Encrytion Standard algorithm was created to help maintain security of communication between senders and recipients so that confidentiality is maintained. This application was created using Android Studio and has installed the JSON web service, so that it can be accessed by Android smartphone devices with the internet. Messages that have been sent will be stored in the MySQL database in the form of scrambled records, so it is necessary to do encryption to find out what the contents of the message are, where the Advanced Encryption Standard Algorithm is cryptography that uses symmetric keys (encryption and decryption keys must be the same). Based on the results of the tests that have been carried out, the functionality of the android-based text message encryption and decryption application at SMA Negeri 2 Kaur runs well as expected and the message sent between the recipient and the sender is kept confidential because the message is encrypted.
An improved approach in CP-ABE with proxy re-encryption

A cryptographic encryption technique converts plaintext into ciphertext, which is non-recoverable by a malicious user without knowing the secret key. The Ciphertext Policy Attribute Based Encryption (CP-ABE) scheme aims for a multicast feature. Different users can decrypt the message if their secret key attributes match with the policy of attributes defined in the ciphertext. In literature, various approaches exist to enhance the naïve CP-ABE scheme. In 2021, Wang et al. proposed the proxy re-encryption-based CP-ABE scheme and presented that it is efficient as its predecessors. However, the proposed scheme follows the variable-length ciphertext where the ciphertext size depends on the number of attributes. Such variable-length ciphertext increases the required number of operations for the decryption, leading to the computation overhead at the receiver side. This paper proposes an enhanced CP-ABE-CL-PRE (CP-ABE Constant Length with PRE) scheme to provide the constant length ciphertext with proxy re-encryption. Our proposed scheme is secure under the Decisional Bilinear Diffie-Hellman (DBDH) problem.
