For this, the dynamic birthmark methods extract the characteristics of programs themselves by running the target programs. Then, the extracted characteristics are compared and calculated the similarities between two characteristics. If the similarity is greater than the given threshold, either of programs is suspected the stolen program from the other. Based on the process, many researchers proposed various dynamic software birthmark methods focused on different aspect of the runtime behaviors. However, the problem is that above detection procedure consumes much time cost. The main cause is the extraction requires the suitable inputs, and the cost for preparing inputs is quite high. Because, the preparation of inputs need the understanding the target programs, and the dynamic birthmarks generally require several inputs for reliable results.","PeriodicalId":318936,"journal":{"name":"Int.

An obfuscation method is to change programs hard to understand by preserving input/output specification. Various obfuscation methods are proposed [2–4], and are implemented to tools, such as Dash-O2, ProGuard3, and etc. In particular, the Identifier Renaming Method (IRM) is widely used, which changes the identifiers in the programs to meaningless names. Because it is easy to implement and to understand the approach [5,6]. However, IRM did not sufficiently discuss the tolerance against attacks, and strength of the protection.

{"title":"The Dependability of Crypto Linked Off-chain File Systems in Backend Blockchain Analytics Engine","authors":"Jongho Seol, Abhilash Kancharla, N. Park, N. Park, Indy Park","doi":"10.2991/IJNDC.2018.6.4.3","DOIUrl":"https://doi.org/10.2991/IJNDC.2018.6.4.3","url":null,"abstract":"A P2P file sharing system, namely Interplanetary File Systems (IPFS) [2,3], provides a service to store huge files in off-chain local storage and partition them into pieces, for each of which with a hash code created and assigned to be posted back in blockchain for reference, referred to as crypto link. IPFS manages hash codes on blockchain in a versioned manner based on the contentaddressed distributed P2P model [4]. It is investigated in this research how to assure the efficacy of managing crypto links along with the performance of the processes with respect to the dependability of blockchain. The dependability [5] in this research is defined with reference to crypto links in a proportional manner and its performance, as referred to as the crypto speed, in an inversely proportional manner, respectively. Also note that the dependability is proportional to the cost such that the more the number of crypto links come in place, the higher its cost is. It is a standard and intuitive practice to partition a large output file into smaller pieces at a certain threshold size provided in the blockchain analytics engine (e.g., 250 KB/partition in IPFS/Hadoop). Crypto link (CL) is defined by the hash address (i.e., a pointer link) stored in the blockchain for a partition of an output file off from a backend blockchain analytics engine. Note that IPFS manages a crypto link to every partition of a file of interest whereas the proposed crypto link scheme is at a reduced number in order to address the cost and performance issue such that one crypto link to the entire file and the links between partitions within a file are maintained by local chains of links. Crypto speed (CS) is defined by the rate of the number of crypto links over the total turnaround time to encrypt all the crypto links (hash addressing) per file. Thus, notice that without loss of generality, the crypto speed increases inverselinearly along with the number of crypto links. A binomial-based [6] dependability model can be expressed as a rather straightforward function of the total number of partitions and the number of crypto links as proposed in this research. At the same time a cost model can be expressed as a function of the ratio of the number of A RT I C L E I N F O","PeriodicalId":318936,"journal":{"name":"Int. J.

This popularity of P2P is due mainly to the many advantages it offers, such as the ease of sharing of computer resources and reducing cost. This paper uses both semi-formal and formal specification methods to model a P2P digital product marketplace. First, models are written in UML, as this is expected to be relatively easy to understand and economic. Then, the models are transformed into a formal notation, object-Z notation. A formally specified and verified model of e-commerce transactions will provide a correct, fail-safe, and robust transaction processing environment for ecommerce. By using both semi-formal and formal methods in the design of the P2P system, we can reason about and create a correct and reliable system quickly and efficiently.","PeriodicalId":318936,"journal":{"name":"Int.

Within last few years, neural networks have been improved tremendously and their performance is even better than humans in some domains, e.g. AlphaGo vs Lee Sedol and Image Net Challenge-2009. It’s a beneficial factor for any parking lot to know that what would be a parking position at any given point in time. If we are able to know in advance that are we going to get parking tomorrow afternoon in a busy super store parking lot, its very beneficial to plan accordingly. In this paper, we predict customer influx in a specific departmental store by analyzing the data of its parking lot. We use this parking data to predict the customer influx and outflux for that parking lot as this parking influx is directly proportional to the customer influx in the store. We use Recurrent Neural Network on the top of two years of historical data. We generate promising results using this dataset by predicting the traffic flow for each hour for next 7 days. We further improve our performance on this dataset by incorporating three more environmental factors along with the parking logs.","PeriodicalId":318936,"journal":{"name":"Int. J.

In this paper, we propose a real-time architecture for e-commerce servers that addresses the problem efficiently. We adopt a framework that permits the appropriate treatment of dynamic behaviours that are data interdependent, and reasoning about the communication protocols and internal mechanisms of client / server relationships in a real-time multi-agents based e-commerce application architecture.","PeriodicalId":318936,"journal":{"name":"Int.
