HidSave: An Image Steganography Technique based on SudoKu Method for Smartphones

In Internet of things (IoT) era, every device in the world is generating and uploading data. These data has to reach end devices for analysis, analytics and visualization. Smartphones are part of IoT era where they can generate and manipulate data. However, the processing power and the storage capacity is limited for this devices to reduce their sizes and their power usage. However, the data generated from these devices have to be secured before transmitted to other end point. In this work, a new steganography image data hiding is proposed, named HidSave. The algorithm is proposed to increase the privacy of the data in one hand and to reduce the storage capacity of the data on the other hand. HidSave adopts SudoKu game in embedding the data in the cover images. HidSave has been implemented and compared to lest significant bit (LSB) and turtle shell hiding algorithm. HidSave has higher embedding capacity and higher PSNR.
