3. SYSTEM ANALYSIS
From the view of data security, the most important thing is cloud computing and new challenges to many threads.
Firstly, traditional cryptography data security cannot be directly adopted so the verification of correct data storage in the cloud must be conducted without explicit knowledge of the whole data. And verifying correctness of data storage in the cloud becomes even more challenging.
Secondly, cloud computing is not third party, and the data stored in the cloud may be frequently updated by the users, including insertion, deletion, modification, appending and reordering etc. and data correctness is very important. And data storage correctness across the multiple servers.
Here we to ensure the correctness of users data in the cloud, we rely on erasure correcting code in the file distribution preparation to provide redundancies and guarantee the data dependability. This construction drastically reduce the communication and storage overhead as compared to the traditional replication- based
File distribution techniques. So whenever data detected during the storage correctness verification, our scheme can almost guarantee the simultaneous localization of date errors, the identification of misbehaving server.
1. Compared to many of its predecessors, which only provide binary results about the storage state across the distributed servers, challenge and further provide the localization of error.
2. The new scheme support secure the efficient dynamic operation on data blocks, updates, deleting and append.
3. Exclusive security and performance analysis
3. Working principle of Electronic Weight Scale
Electronic weight scale are equipped with electronic measuring modules. The electronic weighing machines operate based on the following principle: the force exerted by the load situated on the balance pan is transmitted to the load cell (one or more) which in turn emits an electric signal whose intensity is proportional with the force. The electrical signal is picked up by the electronic balance block, processed, amplified and transmitted to a digital display system (digital mass indicator), the result representing the weight of the mass located on the load pan. A very common solution is to use strain gauges (strain-sensitive transducers). These are generally used for commercial weighing devices with low resolution. The strain gauges are wired as a Wheatstone-bridge to compensate for temperature changes .When the system is not loaded all four resistors are the same and the input of the amplifier is zero. When an object is placed on the pan R1 and R4 are compressed and their resistance decreases, R2 and R3 are strained and their resistance is increased. This causes a voltage difference at the input of the amplifier, proportional to the weight of the object. The strain gauges are wired as a Wheatstone-bridge to compensate for temperature changes .1 : Spring body
2 : Weighing pan
3 : Mounting plate (housing)
4 : Placing and wiring of the strain gauges (R3 and R4 can also be placed on the under side of the beam)
The advantages of electronic/digital weight scale are the plain fact that digital scales are considerably effortless to read. Besides, electronic weight scale will give more accuracy of reading value. Here are some disadvantages to electronic/digital scales, most likely the very regular one being incorrect readings. Several people have complained that when they stand on the scale at one spot and obtain a reading and when they get back after few seconds they get a different reading altogether. Normally, digital scales are good if just anyone make use of it since the mechanism could become worn out after regular use. This instrument need to calibrate after years to get better accuracy.
In relation, French philosopher Jean
Baudillard examines the relationships based on the significations of symbols
and representations in society, constructing simulations ‘perceived to be
reality’ (Baudillard, J, (1998). Baudillard studies how
every individual in a consumerist society, has the choice to escape in “that
which never hides the truth, but hides the fact that there is none”. (Baudillard, J, (1998). As for the Matrix, Morpheus offers Neo (the
main protagonist) a chance to accept the ‘hyperreal’ in the form of a blue pill
to enter the world of fantasy. (Image 3) A world imprisoned form the real – the
Matrix. The term hyppereal was first coined by Budilard through core texts
Simulacra and Simulation (1983); it is the product of the distortions of the
real through endless simulations in the context of radio, newspaper, television
and film. Semiotician Umberto Eco discusses the notion of simulations and
counterfeit realities in a contemporary society through his essay ‘Travels in
the Hyper Reality’, this essay specifically delves in on the artificial
landscapes of the imaginable in America for example Disneyland. His suggestion
is that of American cultural favouring hyperreality, than the actual reality.
The outcome of this pseudo reality is that the duplicate becomes so real and
appreciated, there is less focus on the original the truth. “The pleasure of imitation,
as the ancients knew, is one of the most innate in the human spirit: but here
we not only enjoy a perfect imitation, we also enjoy the conviction that
imitation has reached its apex and afterwards reality will always be inferior
to it”. (Eco, U. (1990). Pg. – (45-47).

3.1 The leadership and management style displayed in this incident.
There are few types of leadership and management style displayed by the CEO and their subordinates in this incident.
On the 9th April 2017, a passenger who is known as Dr David Dao was dragged out violently from the united airlines flight 3411. People took video of that incident in where the officers are dragging Dr Dao who was shouting with helpless and bloody around his arms. Other passengers was screaming to stop but they ignored and took him out from the plane. Dr Dao was one of the four passengers who was randomly selected to leave the plane due to the crews who had to fly on that time.
On the 10th April 2017, the CEO Mr. Oscar Munoz came out with an official statement on the united airline website and also on social media platforms in Facebook and Twitter. The CEO mentioned the word “re-accommodate” to the incident, has brought in anger to the public. In addition, another statement which was delivered to the united airlines employees which was revealed to the public in which the CEO appears to be protecting his employees. This shows the leadership skills that he showed was country club leadership. This style have a high concern on the people and less concern on the production (KOC, Kiliclar, Yazicioglu, 2013). This can be proven when Mr. Munoz did not blame their employees for their action but instead blamed Dr. Dao and called him as “disruptive and belligerent” in a letter which was delivered to the united airlines employees which was revealed to the public. He defended his employees and stood by with them on that situation and said that it was a lesson and could take it as an experience.
On the 12th April 2017, The CEO appeared on the ABC’s Good Morning show, America and addressing that this kind of issue will never happen again. He asked sorry to Dr. Dao and felt ashamed after watching the video and he said will take “full responsibility” on that incident and promised to “make it right”. A review will be conducted by the company by April 30th 2017.
On the April 15th 2017, united airlines had made an announcement which is that they have changed their policy where crew members are no longer allowed to relocate passengers who is already onboard in the plane. The CEO has displayed the coercive leadership skills. This style makes the leader in making a hard decision for the company (Zuned, 2017). This new policy is to ensure in avoiding fiascos which has led to united airlines in crisis situation. Now the airline crews have to check in one hour before the flight takes off. This is to avoid of finding a seat for the crew members after all the passengers have booked their seats already. This changeover is needed in order to recover from the current crisis situation and that is what Mr. Munoz did it.
On the April 27th, the united airlines had settle out with Dr Dao at the court. The both parties had reached to an “amicable settlement” after Dr Dao suffered several injuries after being forcibly removed violently from the plane, which is stated from Thomas Demetrio (Business insider, 2017). Mr. Munoz has said that he is going to do what is right and he has did it. Moreover, the united airlines took full responsibility for the incident that happened in the united airlines flight 3411, deprived of trying to blame others.
