JPEG image encryption technology converts original images into noise-like images that do not contain any useful information, ensuring the security and privacy of valuable images. At present, most existing work may not achieve a good balance between file size preservation and security. Therefore, in order to solve this issue, we present a new JPEG image encryption scheme. In our scheme, we first perform predictions on the DC coefficients, and then implement averaging operation on the prediction error, which provides security effects while effectively decreases the encoding length. To further strengthen the diffusion performance, block permutation excluding the DC coefficients is executed. In addition, in order to control the file size growth, AC coefficients are protected by the run-based RS (run/size) pairs permutation. The experimental results show that the proposed scheme can not only effectively preserve the image file size, but also offers satisfactory security.

Corn leaf diseases, consisting Common Rust, Gray Leaf Spot, and Blight, pose significant threats to worldwide farming by affecting crop harvest and standards. Blight causes rapid defoliation of plants;Common Rust brought on by Puccinia sorghi and Grey Leaf Spot reduces photosynthesis and yields losses. Early and accurate detection is crucial for timely intervention, reducing chemical dependency, and ensuring food security. This study leverages Residual Networks (ResNet) to advance disease detection. ResNet's deep residual learning architecture efficiently handles complex image classification tasks. Trained on maize leaf images, the ResNet model achieved 96% accuracy in classifying leaves into common rust, gray leaf spot, blight, and healthy categories. A model's high precision and recall significantly enhance detection accuracy. This work supports sustainable agriculture, promotes resilient agricultural practices, and contributes to food security by improving disease control and crop management through advanced technology.

With the increasing popularity of the internet of Things (IOT) and devices getting smarter, this research has presented an idea to reform the weather information for precision farming. In this study, the information of weather forecast was prepared for air quality control systems using the sensor of network systems to increase the quality of organic vegetable in Thailand under the condition of Thailand weather The prototype model was described by the devices of embedded systems, which is gotten from the temperature and humidity sensor. Therefore, if there is any data from the input sensor, the users are allowed to access and granted to use this system, then, the log data are transmitted by the internet to the designation website by using a Wi-Fi module (ESP8266). As a result, it can be used the machine learning algorithms for implementing of monitor controller, which is applied for analyzing and collecting data to air quality control in green house

Brain computer interfaces (BCI) are applications that allows user to interact with their environment through their brain waves patterns, in this context the detection of eye blinks seems a good way to perform basic interactions. Electroencephalography (EEG) are methods that allows recording of brain waves through invasives or non invasives methods, in the cases of BCI application the lesser the invasiveness the higher the applicability. As this work will focus on pattern recognition within brain waves we developped a machine learning based approach to detect and classify different actions. Additionnaly the differentiation for each eye allows better interactivity for BCI applications.
