Description: 本專題分為3大部份
1. 對單一圖片做邊緣檢測後, 統計其複雜度, 再以 Delaunay 三角網來分割複雜度較高的圖形, 將此圖形之三角網的三點座標與RGP值
取樣後壓縮儲存, 及達成壓縮目的.
還原部份為, 以線性內插則是將取樣後的三角網三點內插後還原之原理, 還原單一影像, 再將所有還原之影像串連撥放即完成之影片還原.
2.讀取RS-232接至RFID門禁系統, 讀取Myfair悠遊卡之卡號,
進行身份辨識後, 可選擇需要觀賞之影片.
3.取得卡號後, 讀取輸出資料庫做判別動作, 使用者可對資料庫做登入登入新增刪除等動作.-The project is divided into three major parts
1. To do edge detection on a single picture, the statistics of its complexity, then complexity of Delaunay triangulation to partition a high degree of graphics, this graph of the triangulation point coordinates and RGP values
After the compression sample storage, and compression to achieve the purpose.
Restore some order to the linear interpolation of valid sampling triangle mesh after three, after interpolation to restore the principle of reduction of a single image, then restore the image to link all of the completed film to restore Playback.
2. Read RS-232 connected to the RFID access control system, the card number read Myfair Easy Card,
Identity recognition, the option need to watch the video.
3. To obtain card numbers, read the output database to do discrimination action, the user can log in sign new database to do delete and other activities.

Description: 关于现有的基于WLAN，蓝牙以及RFID等的定位算法的综述和系统比较。是content-aware下的新兴的应用领域，有很大发展空间-Location, Localization, and Localizability
Location-aware technology spawns numerous unforeseen pervasive applications in a wide range of living, pro-
duction, commence, and public services. This article provides an overview of the location, localization, and localizability
issues of wireless ad-hoc and sensor networks. Making data geographically meaningful, location information is essential for
many applications, and it deeply aids a number of network functions, such as network routing, topology control, coverage,
boundary detection, clustering, etc. We investigate a large body of existing localization approaches with focuses on error
control and network localizability, the two rising aspects that attract signi¯ cant research interests in recent years. Error
control aims to alleviate the negative impact of noisy ranging measurement and the error accumulation e® ect during coope-
rative localization process. Network localizability provides theoretical analysis on the per

Description: Cryptanalysis of INCrypt32 in HID s iCLASS Systems
ChangKyun Kim, Eun-Gu Jung, Dong Hoon Lee, Chang-Ho Jung, and Daewan Han
Category / Keywords: secret-key cryptography / INCrypt32, HID s iCLASS, RFID, reverse engineering, chosen message attack.-Abstract: The cryptographic algorithm called INCrypt32 is a MAC algorithm to authenticate participants, RFID cards and readers, in HID Global s iCLASS systems. HID s iCLASS cards are widely used contactless smart cards for physical access control. Although INCrypt32 is a heart of the security of HID s iCLASS systems, its security has not been evaluated yet since the specication has not been open to public. In this paper, we reveal the specication of INCrypt32 by reverse engineering an iCLASS card and investigate the security of INCrypt32. As a result, we show that the secret key of size 64 bits can be recovered using only $2^{18}$ MAC queries if the attacker can request MAC for chosen messages of arbitrary length. If the length of messages is limited to predetermined values by the authentication protocol, the required number of MAC queries grows to $2^{42}$ to recover the secret key.
