The article proposes a multi-level algorithm for protecting information transmission by means of a wireless router and Raspberry Pi. The proposed algorithm is implemented on the basis of separate encryption tools operating in parallel with secure communication channels. By directing traffic to anonymous and protected servers (Tor) and by encrypting information and using a DNS proxy in parallel, the information is available only to legitimate users

In this work, a development of stock counting system using PDA is presented. The design and development issues are studied for the case of a superstore in Thailand. The stock counting is a tedious work in a department store. Employees need to physically walk down the shelves and count the amount of items each day. The amount of items is compared to the amount in the system to check for the loss of items every day. For a large-size department store, many employees need to spend lots of time to perform the tasks. Introducing the use of PDA together with the barcodes of the products will help automate the process, save time, and reduce the errors for checking the stock counts. In this paper, the design of system presents in the aspect of 1) the PDA software client and server sides 2) wireless access point installation costs and plans. After the development, the system is employed. Its efficiency is compared to the manual counting and the user satisfactory is evaluated.
