“Where can we find them?” “You will have to follow the path there.” He pointed sleepily to a trail in the sand. “It’ll pass through a forest and then veer nor’east toward Shadow Mountain.” The captain raised his eyebrow skeptically. “That’s if you choose to accept your quest.” I glanced at Mason, who was crossing his fingers. “Sure.” I shrugged. “It’s better than becoming a sea monster biscuit.” “That’s fine, lad.” The captain pulled a Swiss Army knife from his trouser pocket and handed it to…

What is RxNorm? RxNorm is a reference terminology that applies standardized names to medications. Its creation was motivated by need for a standard terminology for representing drugs. These names are then linked to the drug names used in pharmacy software programs that manage patient medications and interactions (e.g. Micromedex, Medispan, First Databank). Rx norm also includes the National Drug File -Reference Terminology (NDF-RT) that is used by the Veterans Health Administration (NIH U.S.…

criminals, all the same. Put money in front of them and they would all do the same thing, take it. It does not matter what job you have or how much money you make, there will always be ambition for more. Everyone was taught money was the key to success and success was the key to a better life, this is what makes it so easy for people to be corrupt. In The White Tiger by Aravind Adiga and 419 by Will Ferguson corruption among men of the law and politicians plays a huge role. In The White Tiger…

Sensitive information provided during the registration process would be subjected to the encryption and data hiding process. 4. The patient profile would display the encrypted data details but the plaintext can be viewed if the patient supplies the key to decrypt which would replace the encrypted data with the plain…

Blown to Bits – 15 points each No, it shouldn’t be illegal to encrypt data. It should be legal because the Government shouldn’t have an automatic right to read anyone’s private messages/information at any time. One pro of end-to-end encryption is that data is secured when it travels from a source to its destination. It also offers high flexibility for user in selecting a data to encrypt. Another pro is that we can easily integrate with the existing solution. We can just add an…

The Counterfeit Coins Problem is a well-known complex search problem in mathematics as well as in computer science. It can be related to the data structure (such as binary tree) computer program, algorithm, Graph Theory, Therefore researching this problem is meaningful. The Counterfeit Coins problem can be described as given a set of n look-alike Coins containing One Counterfeit which is a bit heavier or lighter than the genuine Coins. The objective is to find the Counterfeit Coins in minimum…

In this case which involves an active warden, however, the message needs to look innocuous and hence cryptography fails. Steganography comes to the price¬owners, rescue. The prisoners’, with a strong intention of planning an escape, have already exchanged a code word before they were captured. They use this codeword to secretly exchange messages in the process…

2 DESCRIPTION OF THE USEA 2.1. Data Encryption phase USEA encrypts 512-bit blocks of plaintext to cipher text by a 256-bit main key that from now we call it MK. In default, USEA consists of 20 identical rounds, but we can increase or decrease the rounds for amplification of our algorithm in specific hardware or software implementation. Note that Decreasing rounds of algorithm reduces its security against attacks. USEA uses different algebratic, logic and arithmetic operations for data…
