“…This method can be used as an effective alternative when it is difficult to obtain multivariate information data [48]. (3) In terms of the protection of personal information security, the prediction model is built without the need to collect pedestrian flow information through surveillance or mobile devices, which respects the personal information and privacy of the counted walkers [49].…”

Designing reasonable commercial transportation space is of great significance to enhancing the overall value of commerce. This study takes the classic cases of three typical plans of commercial wholesale centres (CWCs) as the research object, uses space syntax to analyse the connectivity of the architecture of the traffic space, simulates the current situation of the pedestrian flow distribution through ArcGIS, and constructs a multiple regression model for the association between connectivity and pedestrian flow distribution. The results of this study show that for CWCs with a single business type and a focus on traffic efficiency, the distribution of the pedestrian flow is most affected by the main entrance and the vertical traffic distribution. For different types of planes, when the commercial traffic space has strong symmetry, its group relationship is more concise. While a uniform form is more conducive to achieving a balanced distribution of commercial traffic, the asymmetry of the plan layout helps to establish a psycho-spatial map for the visitors. In addition, the commercial value of the first floor is greatly influenced by the layout of the building entrance, and the commercial value of the second floor is greatly influenced by the location of the vertical transportation. In conclusion, when commercial building development planning is in the stage of traffic flow design, the use of space connectivity traffic data can assist in the selection of construction plans and predict the distribution of the economic value in CWCs.

Information security is very significant needs to be secured due to people relying on networks and communication. Therefore, protecting information is a major challenge with the number of users increases rapidly in recent years. The aim of this article is to review Confidentiality, Integrity and Availability (CIA) in information security. This article focuses on the issues of information security and the requirements of information security. The articles, journals and conference papers are reviewed by researchers were published in 2016-2021. Security issues are analyzed in the recent methodologies. The result of the relationship between CIA in each information security requirement is at a moderate level. It is suggested cybersecurity risk awareness program for society is needed. Therefore, every user could get full advantages in networks and digital platforms.

“…Consequently, many studies on video encryption have adopted joint compression and encryption, and the proposed method also benefits from this encryption type. In addition, various video encryption methods exist, such as fully layered, selective, and perceptual encryption [10]. However, the region of interest (ROI) encryption process for HEVC/H.265 is quite different from that for AVC/H.264.…”

The region of interest (ROI) encryption in the video can reduce the complexity of calculation and improve encryption speed by encrypting only the area containing critical visual information. Above all, ROI encryption can expand the utilization domain (e.g., video surveillance), unlike general encryption methods that de-identify the entire frame. However, the traditional ROI encryption process in high-efficiency video coding (HEVC)/H.265 is more complex than in advanced video coding/H.264, and the encrypted area tends to be wider than the ROI. Thus, cryptographic algorithms are applied outside the ROI, which wastes computing resources and restricts the visual information that needs to be provided. Therefore, this paper proposes a coding unit (CU)-based ROI encryption for HEVC/H.265 video. The proposed method selectively encrypts HEVC/H.265 parameters, such as the intra prediction mode, motion vector (MV), MV sign, transform coefficient (TC), and TC sign, which have significant visual influence, and adopts the tile concept for parallel processing frames. The CU-based ROI encryption reduces complexity by identifying the encryption area based on the CU coordinates, applying encryption only to the CUs associated with the ROI. This approach can preserve the area around the ROI by restricting the reference area. Moreover, it provides up to about 30% faster encryption speed than the traditional method while maintaining performance (i.e., peak signal-to-noise ratio and structural similarity index measure).
