Some common biometric techniques include:

1. Fingerprint recognition
2. Signature dynamics
3. Iris scanning
4. Retina scanning

 Create a Dashboard to provide insight about your data.

Use the Nielsen data provided from the link below:

NIELSEN TOPLINE RATINGS FOR SUBSCRIBING RADIO STATIONS

https://tlr.nielsen.com/tlr/public/market.do?method=loadAllMarket

Select radio market data from 1- 3 Florida markets (cities). Example: Walton Beach – Destin, FL

Export the data into an Excel spreadsheet, labeling the content by market/city.

Part A: Add a PivotTable to display summary data.

1. Create value fields
2. Create row dimensions
3. Add a basic filter for Model
4. Insert a Slider for Months
5. Insert a Timeline for      Date

Use “Format as  Table” to format the PivotTable using colors of your choice. (Several PivotTable styles are available to choose from).

Note: In a Pivot Table report, the dimensions are the descriptive attributes used for labeling, grouping, and aggregating the data – for example, Type and Date. The measures are the numeric data points that can be used in mathematical operations; for example, sales, quantity, etc.

Part B: For this part, you are required to perform only one of the following activities:

.

1. Add a Bar Graph to       show the top category of products, providing additional insight about       your data. You choose the appropriate dimension(s) and measure(s), and       you choose the layout and design.
   Ensure       that your PivotChart is relevant and is able to answer questions about       your data.

Write a program, myfilehide2, that encrypts a file — ASCII or binary — and saves the encrypted file. myfilehide2 reads from stdin a string that specifies the file to be encrypted followed by an integer. For example,

% myfilehide2
a.out 7

myfilehide2 saves the encrypted content in a new file whose name has “.E2” added as a suffix. After doing so, the app deletes the original file by calling remove(). In the above example, a.out.E2. We restrict input file names to be less than 15 characters and output file names to be less than 18 characters to account for the 3 character suffix. Spaces are not allowed in a file name. The filename and number must be separated by one or more space (‘ ‘) or tab (‘\t’) characters. The number must be a single digit — either 0, 1, …, 7 — and end with ‘\n’ which is generated on stdin when the ENTER/RETURN key is pressed on our lab machines. All other input of different format are disallowed and should result in a suitable error message on stdout followed by app termination by calling exit(1).

use the library function getchar() to read the input byte-by-byte. When a space character or tab character is encountered, assume the filename has ended and store it as a string in a 1-D char array of size 16. Of course, that is assuming that the filename has not exceeded 15 characters. Instead of the constants 15 and 16, use the C preprocessor directive #define to specify your own macro to reduce the potential for run-time bugs. Read the single digit (0, 1, …, 7) into variable, char numpos, and convert numpos into a decimal number, unsigned int decpos, when interpreted as a decimal number. For example, the ASCII character ‘3’ stored in numpos is convered to the decimal number 3, not the decimal encoding of the ASCII character ‘3’ which is 51.

Do not use any string processing library function to perform the input parsing task. The parsing chore can be implemented with a few lines of code. Delegate the input parsing task to

void inputcheck(void);

which stores a valid filename input a global 1-D char array. Make the variable numpos also global. 

After inputcheck() returns (it may not return if the input is ill-formatted), main() opens the input file to read and creates an output file with suffix “.E2” to write the encrypted bytes. If either of the two operations is unsuccessful, main() prints a suitable error message to stdout and terminates by calling exit(1). Otherwise, like in Problem 2, lab3, myfilehide2 reads the content of the input file byte by byte using fgetc(). Unlike myfilehide, myfilehide2 flips the bit value at the bit position specified by decpos and writes the resultant byte into the output file. For example, if an input byte has bits 00001111 and decpos equals 2, the encrypted byte is 00001011. Note that the rightmost bit at position 0 is considered the least significant bit. As with myfilehide, myfilehide2 has the property that running the app again on the encrypted file with the same digit as second arguments decrypts the file. Perform a similar cleanup as myfilehide so that the encrypted file with suffix “.E2” is deleted. Use Makefile to compile your app. Test and verify that it works correctly on mac terminal.

Understanding that you cannot simply overwrite previously deployed smart contracts, contrast approaches to deploying traditional applications and blockchain apps. Does blockchain make deployments easier or harder? Are there any potential risks when deploying blockchain apps that either don’t exist in traditional environments or aren’t as prominent? What should a development organization do differently to mitigate these risks?

• Contrast approaches to deploying traditional applications and blockchain apps.
• Explain whether blockchain make deployments easier or harder.
• Identify any potential risks when deploying blockchain apps that either don’t exist in traditional environments or aren’t as prominent.
• Describe what a development organization should do differently to mitigate these risks.

Identify a case of corporate fraud by finding a current event or by researching historical cases. After finding a case, complete the following in your initial discussion post:

• Briefly summarize the case, including what happened, who was involved, and what damages were incurred.
• Note how the fraud was detected and discuss any red flags that appeared prior to detection.
• Could an accounting and finance system have helped deter this fraud? If yes, how? If no, why not?
• Are there any specific business policies and procedures that could have been in place that would have prevented the fraud from occurring? Explain.
• Embed course material concepts, principles, and theories, which require supporting citations along with at least two scholarly peer reviewed references supporting your answer. Keep in mind that these scholarly references can be found in the Saudi Digital Library by conducting an advanced search specific to scholarly references.
• Reply to at least two of your peers’ initial posts. These replies need to be substantial and constructive in nature. They should add to the content of the post and evaluate/analyze that post’s answers. Normal course dialogue doesn’t fulfill these two peer replies but is expected throughout the course. Keep in mind that within your initial post, answering all course questions is required.
• Use Saudi Electronic University academic writing standards and APA style guidelines.

Be sure to support your statements with logic and argument, citing all sources referenced. Post your initial response early, and check back often to continue the discussion. Be sure to respond to your peers’ posts as well.
