when you re working i mean, we re looking at images right now of people climbing over a pile of what we would call rubble. how do you what do you where do you begin? so, you know, so what they re doing here, in this particular footage, they re obviously searching by hand. that s why they have the buckets. they re taking brick by brick, stone by stone, debris by debris, into a bucket and taking it off the pile, looking for voids, looking to see they ll bring cameras in. sometimes they ll have the dogs walk on the pile first. and i assume it s got to be done kind of by hand, at this stage, because you don t want a backhoe going to an area where there may be somebody. right. so for really obviously, large, heavy structures, you re not going to be able to move them, so then you get the heavy equipment to move it, and then once that s de-layered, you can do the hand by hand, piece by piece, doing the different devices, infrared, heat-sensitive equipment. do you divide it
Abstract
As cloud storage has been widely adopted in various applications, how to protect data privacy while allowing efficient data search and retrieval in a distributed environment remains a challenging research problem. Existing searchable encryption schemes are still inadequate on desired functionality and security/privacy perspectives. Specifically, supporting multi-keyword search under the multi-user setting, hiding search pattern and access pattern, and resisting keyword guessing attacks (KGA) are the most challenging tasks. In this article, we present a new searchable encryption scheme that addresses the above problems simultaneously, which makes it practical to be adopted in distributed systems. It not only enables multi-keyword search over encrypted data under a multi-writer/multi-reader setting but also guarantees the data and search pattern privacy. To prevent KGA, our scheme adopts a multi-server architecture, which accelerates search response, shares the workload, and

it, you know. we had been searching quite a bit of area, covering it really, really well, we were using gps technology so we knew exactly where we had been searching and we haven t found another piece of evidence that led us away from that area and we hadn t smelled anything strange, we hadn t found anything strange. we were like, well, that only means that she s just still moving. that s why we haven t found her. tell us about the moment that you spotted her while you were in the helicopter. it was it was it was it was magic. it was it was elation. we re flying up, going up this what we call a george coming up, there is a waterfall and stream and pretty much we re going up with the helicopter, there was a waterfall, there was a waterfall, there was a stream, a waterfall, a stream. we are hanging off these helicopters and, you know, we were having to turn around. we were at the end of this search pattern because the helicopters only have a certain
